What is .NET Development Framework?

The.Net framework was initially designed to let developers create programs that only worked on Windows Platform. Microsoft Corporation launched many versions of Net Framework after the first. Version 4.8 is the latest. There are now two types of.NET frameworks on the market: the.NET framework and the dot NET framework. These.NET versions are both very promising because they support almost all programming languages.

C# and Visual Basic are the two major languages that are supported, but they also support more than 50 languages. This makes them a very versatile framework for app development. The.NET framework is not restricted as it can be used for both Web and form-based applications. Microsoft.Net Framework is a versatile development platform which can be used for creating web services.

Evolution of .NET Framework

Microsoft introduced the.NET Framework in 2002. Since then, this technology has become the fastest and most convenient way to develop apps. .NET is a powerful and effective tool that has a large class library. This allows developers to easily create any app in any language. Interoperability, scalability and its ability to run any language make it a common runtime language.

Microsoft began developing.NET during the 90s, when they were working with the Next Gen Windows series. Since the launch of Next-Gen was delayed, the release of the beta version of.NET framework was also delayed. Later in 2002, the version that was expected was released. The first version was compatible with Windows 98 and Windows XP. It was designed with key features of DLL libraries and object-oriented web design in mind.

They developed new versions with more advanced features. After version 1, there was version 1.1,.NET Framework 2.0, version 3.0 version 3.5 version 4.0 version 4.5 version 4.6 and 4. The latest version 4.8, the most stable version, was released in April 2019. Migrating from ASP.NET is a simple task.

.NET is a popular choice for many companies because it has a proven track record and trust. As a result, more businesses are interested in using.NET. It is important to know the trends that make.NET so successful and ahead of all other frameworks. Let’s begin by exploring the latest .NET development trends.

Benefits of AutoMapper

AutoMapper

When developers employ AutoMapper for mapping the properties of two different types of objects they have proven its ability as an object-to object mapper library. AutoMapper makes it easy to set up types for mapping and testing. Methods for mapping objects perform the conversion from one type of object to another. AutoMapper offers attractive standards to help you avoid the hassle with manually converting one kind to another. Since issues in one layer are often in conflict with issues in the other object-object mapping produces partitioned models where issues in a specific layer only affect specific types at this level.

Benefits of AutoMapper

Maps that are easier to use

If you’re using AutoMapper You can test the mapping using Unit tests at one place to save time and energy.

Code that is Clean

Transferring data among distinct objects requires the smallest number of lines. A shorter development time is directly derived from a simpler program since it takes less effort to create maps between objects.

Excellent maintainability

Similar mappings between both items is centralized in one place that makes it much easier to manage

Let’s See How to Use AutoMapper Library

Step 1: Here are the Employee entity and Employee view model classes.

 
                        public class Employee
                        {
                        public Guid Id { get; set; } = Guid.NewGuid();
                        public string Name { get; set; }
                        public string Email get; set; }
                        public DateTime CreatedDate { get; set; } = DateTime.Now;
                    
                        
                        
                        
                            public class EmployeeViewModel
                        {
                        [Required]
                        public string Name { get; set; }
                        [Required]
                        public string Email { get; set; }
                        }

Step 2: In order to implement AutoMapper, first we should download a NuGet Packages to our project:

Step 3: Create a mapping profile that specifies how to map the properties between the Employee entity and the EmployeeViewModel.

                        
                            public class MappingProfile: Profile
                            {
                            public MappingProfile()
                            {
                            CreateMap()
                            .ForMember(dest=> dest.Name, opt=> opt.MapFrom(src => src.Name))
                            .ForMember(dest=> dest.Email, opt=> opt.MapFrom(src => src.Email));
                            }
                            }

Step 4: After creating the proper mapping profile class, the next step is to register AutoMapper as a Service in the Program.cs file.


                                // Add services to the container,
                                builder.Services.AddA flapper(typeof(Program).Assembly);
                                builder.Services.AddControllersWithViews();
                                vår app = builder.Build();

Step 5: We can map Employee entities with EmployeeViewModel in the controller methods.


                        
                        using AutoMapper:
using Microsoft.AspNetCore.Mvc;
using PracticeAPP.Models;
using PracticeAPP.Models.Entities;
using PracticeAPP.Models.ViewModels;
using System.Diagnostics;
namespace PracticeAPP.Controllers
                    
public class HomeController: Controller
{
private readonly ILoggerloggerlogger;
private readonly IMapper_mapper;
public HomeController(ILoggerlogger, IMapper mapper)
{
_logger= logger;
_паppег= mapper;
}
public IActionResult Index()
{
return View();
}
public IActionResult Register(EmployeeViewModel model)
if (!ModelState.IsValid)
return BadRequest(ModelState);
var employee= _mapper.Map(model);
return View(employee);
}

                                //Config Swagger for Dev
                                if (app.Environment.IsDevelopment())
                                {
                                app.UseSwagger();
                                app.UseSwaggerUI();
                                }

CacheManger

  • To help the cache providers that are part of .NET features that are enhanced for implementation, CacheManager was built as an open-source .NET Network library for C#. C# programming language.
  • By using CacheManager, the .NET CacheManager library, developers can streamline their work and deal with even the most complex cache scenarios with just two pages of code.

Benefits of CacheManger

Seamless Coding

Because of the possibility for the possibility of concurrency, making changes to a value in a distributed environment can be a challenge. CacheManager removes the complexity and allows you to accomplish this in a single page of your code.

Sync Mechanism

It is possible to keep local instances in sync by using multiple layers with a distributed cache layer and running multiple instances of your application running.

Cross-platform Compatible

CacheManager has been updated to include cross-platform compatibility. It has tested for cross-platform compatibility across Windows, Linux, and iOS because of the new .NET Core/ ASP.NET Core structure of the project and the libraries.

Let’s See How to Use CacheManger Library

Step 1: Add Configuration for CatcheManager in the Program.cs file.

                            
    services.AddLogging (c => c.AddConsole() .AddDebug().AddConfiguration (Configuration));
    services .AddCacheManager Configuration (Configuration,cfg=> cfg.WithMicrosoftLogging (services));
    services .AddCacheManager  (Configuration, configure: builder => builder. WithJsonSerializer());
    services .AddCacheManager  (inline => inline. WithDictionary Handle());
    services .AddCacheManager();

Step 2: Now, We will use CacheManager in Values Controller.

                        

                     
[Route("api/[controller]")]
public class ValuesController: Controller
{
private readonly ICacheManager _cache;
public ValuesController(ICacheManager valuesCache, ICacheManager intCache, ICacheManager dates)
{
_cache = valuesCache;
dates.Add("now", DateTime.UtcNow); 
intCache.Add("count", "1");
}
// DELETE api/values/key
[HttpDelete("{key}")]
public IActionResult Delete(string key)
{
if (_cache.Remove(key))
{
return Ok();
}
return NotFound();
}
 
// GET api/values/key 
[HttpGet("{key}")]
public IActionResult Get(string key)
{ 
var value = _cache.GetCacheItem(key);
if (value == null)
{ 
return NotFound();
}
return Json(value.Value);
}

// POST api/values/key
[HttpPost( “{key}")] 
Public IActionResult Post(string key, [FromBody]string value)
{
if (_cache.Add(key, value))
{
return Ok();
}
return BadRequest("Item already exists.");
}
// PUT api/values/key
[HttpPut("{key}")]
public IActionResult Put(string key, [FromBody]string value)
{
if (_cache. AddOrUpdate(key, value, (v) => value) != null)
{
return Ok();
}
return NotFound();
}
}

Dapper

To ease communication between applications and databases You could make use of Dapper which is an Object-Relational Modeler (ORM) that can be described more specifically. Micro ORM that works with SQL server. Dapper lets you write SQL statements using the same format as SQL Server. Dapper’s speed is unbeatable since it doesn’t modify SQL queries made within .NET. Dapper is able to execute procedures either in synchronous or asynchronous fashion.

Benefits of Dapper

Size : It’s light, and simple to operate and access.

Security : Dapper is not affected by SQL Injection so that you can run parameterized queries without restriction. The assistance offered by several databases is a further important aspect.

Database Compatibility : Dapper can be used with a wide array of database services. Dapper is an extension of ADO.NET’s IDbConnection that adds convenient methods to interact using your database.

Let’s See How to Use Dapper Library

Step 1: Let’s start by creating a new Entities folder with two classes inside

                            

                          
public class Employee
{
public Guid Id { get; set; } Guid. NewGuid();
public string Name { get; set; }
public string Email { get; set; }
public DateTline CreatedDate { get; set; } = DateTime.Now;
}
 
public class Company
{
public int Id { get; set; }
public string Name { get; set; }
public string Address { get; set; }
public string Country { get; set; }
public List Employees { get; set; } = new List();
}

Step 2: Now, we are going to create a new Context folder and a new DapperContext class under it: 

                            

                           
public class DapperContext
{
private readonly IConfiguration _configuration;
private readonly string _connectionString;
public DapperContext(IConfiguration configuration)
{
_configuration = configuration;
_connectionString =_ configuration.GetConnectionString("SqlConnection");
}
public IDbConnection CreateConnection()
=> new SqlConnection(_connectionString);
}

Step 3: We have to do the registration in the Program class:

                            

                          
builder.Services.AddSingleton();
builder.Services.Add Controllers

Step 4: Now We have to create Repository Interfaces and Classes and Then, let’s implement this method in the class:

                            

                           
public interface ICompanyRepository
{
public Task> GetCompanies();
}
using Dapper;

Ocelot

Ocelot can be described as an asp.net core library that acts as an API bridge to .NET APIs. It is targeted at a group of .NET developers that require an interface for their decentralized services as well as microservice functionality. However, it can work on any platform where ASP.NET Core is accessible and can be used with any application that can understand HTTP.

It tricked its HTTP Request object into a state it is able to determine by its parameters, until it is transformed through a middleware for request building. A HTTP request message is created from there, and then used to connect with an online service. The Ocelot pipeline is completed with the sending of the request to middleware. Following that the middleware ceases to make calls. middleware will be made. When requests are made upstream along the Ocelot pipe, they will be followed by an answer by the service downstream.

This is how the Ocelot API Gateway Works in our project.

Benefits of Ocelot

Usability : Request aggregation, routing web sockets, rate-limiting authentication, authorization caching, load-balancing and configuration. are just a few of the numerous applications for this net central module.

Let’s See How to Use Ocelot Library

Step 1: You should add Ocelot to the service container by calling the AddOcelot method in the ConfigureServices method of the Startup class as shown below:

                            

                           
public void ConfigureServices(IServiceCollection services)
{
Action settings = (x) =>
{
x.WithMicrosoftLogging(log =>
{
log.AddConsole(LogLevel.Debug);
}).WithDictionaryHandle();
}; services.AddOcelot(Configuration, settings);
}
public async void Configure(IApplicationBuilder app, IHostingEnvironment env )
{
await app.UseOcelot();


}

Run the projects.

Now make sure that you’ve made all projects as startup projects. To do this, follow these steps:

1. In the Solution Explorer window, right-click on the solution file.

2. Click “Properties”.

3. In the “Property Pages” window, select the “Multiple startup projects” radio button

4. Click Ok.

Autofac

To support .NET programs, Autofac provides an IoC container. It allows programs to be flexible when they grow in terms of size and complexity, by regulating inter-class relations. To accomplish this aim, developers can utilize standard .NET classes as elements.

Benefits of Autofac:

Flexibility : Autofac doest-net library manages inter-class dependencies that allow programs to be flexible, even when their complexity and size increase.

Community support : The majority of ASP.NET developers select Autofac as their preferred DI/IoC container because it’s compatible with .NET Core architecture without any problems.

Let’s See How to Use Autofac Library

Step 1: Install Autofac and Autofac.Extensions.DependencyInjection nuget package

Step 2: The code in program class will change to use Autofac as the DI container.

builder.Host. UseServiceProviderFactory (new AutofacService ProviderFactory());

Step 3: We will create a class and interface with a method to return a static string.

                            

                            
using PracticeAPP.Contracts;
namespace PracticeAPP.Repository
{
public class AutofacRepository: IAutofacRepository
{
public string getStringAutofac()
{
return "Hello Autofac Data";
  }
 }
}
 
namespace PracticeAPP.Contracts
{
public interface IN Autofac Repository
{
   public string getStringAutofac();
 }
}

Step 4: Finally, I will update the Controller to use the interface to return the constant text “Hello Autofac Data” as a return to the GetStringAutofac method.

                            

                           
using Microsoft.AspNetCore.Mvc;
using PracticeAPP.Contracts;
namespace PracticeAPP.Controllers
{
public class AutofacController: Controller
{
private readonly IN Autofac Repository _autofacRepository;
public AutofacController(IAutofacRepository autofacRepository)
{
this._autofacRepository=autofacRepository;
}
// GET api/values
[HttpGet]
public string GetStringAutofac()
{
return _autofacRepository.getStringAutofac();
  }
 }
}

MediatR

A person who describes the dynamic between several parties is described as the mediator pattern within the area of development software. This pattern is categorized as a behavioral one because it is able to modify the behavior of the program while it is in use.

MadiateR is a basic application of the mediator within .NET. Request/response, instruction, questions as well as notifications and instances. In this library, both the synchronous and asynchronous functions are enabled by the clever distribution and dispatching C# generic variance.

MediatR could be viewed to be an “in-progress” version of Mediator that allows the creation of CQRS systems. In the plethora of useful .Net libraries, MediatR stands out.

Benefits of MediatR:

Seamless Coding

Because of the possibility for the possibility of concurrency, making changes to a value in a distributed environment can be a challenge. CacheManager removes the complexity and allows you to accomplish this in a single page of your code.

Reduced Dependencies

The direct dependence on numerous objects can be reduced by using the MediatoR pattern to make them cooperative.

Communication

It serves as the primary means of interaction between your user interface and your data storage system. Classes provided by MediatR in .NET Core facilitate efficient, freely linked communication between numerous objects

Let’s See How to Use Autofac Library

Step1: Create a new web API project.

Step 2: Create a folder with these three classes.

Step 3: ApiRequestModel: This class represents a request for API.

                        

                        
using MediatR;
namespace MediatrApiProject.APIFolder
{
public class ApiRequestModel: IRequest
{
public int Number { get; set; }
}
}
— IRequest<> It represents a request with a response.

Step 4: ApiResponseModel: This class represents a response of API.

                        

                        
namespace MediatrApiProject.APIFolder
{
public class ApiResponseModel
{
public string Response { get; set; } = string.Empty;
}
}

Step 5: ApiHandler: And this class keeps the Media R

                        

                     
using MediatR;
namespace MediatrApiProject.APIFolder
{
public class ApiHandler: IRequestHandler
public async Task Handle(ApiRequestModel apiRequest, CancellationToken cancellationToken)
{
var response = $"Number :- {apiRequest.Number}";
return new ApiResponseModel
{
Response=response
};
}
}

Step 6: ApiHandler: MediaR

                        

                        
using MediatR;
using Microsoft.AspNetCore.Mvc;
namespace MediatrApiProject.Controllers

[ApiController]
[Route("api/[controller]")]
public class APIControllerBase : ControllerBase
{
private ISender _mediator;
protected ISender Mediator => mediator ??= HttpContext. RequestServices.GetService();
 }

Step 7: ApiHandler: And this class for MediaAPIFolder

                        

                        
                        using MediatrApiProject.APIFolder;
using Microsoft.AspNetCore.Mvc;
namespace MediatrApiProject.Controllers
{
public class HomeController: APIControllerBase
{
public HomeController() { }
[HttpGet(nameof(ApiController))]
public async Task> ApiController(int number)
{
    try
    {
       var request = new ApiRequestModel { Number = number };
       return await Mediator.Send(request);
    }
    catch (Exception ex)
    {
         throw;
    }
   }
  }
}

Step 8 : Test this API using swagger.

Fluent Validation

Fluent Validation is an .NET Framework class library used to build validation rules that can be highly constructed. Fluent Validation can be a fantastic alternative to annotations of data for validation of models. It allows for a greater separation of problems as well as a better control of validation rules and makes them simple to understand and test. The Lambda expression is used to verify the authenticity of. When you require complex validation for users’ data Fluent Validation is a great tool.

Benefits of Fluent Validation

Open-source

Fluent Validation is an .NET framework-based class library that allows making validating rules which are well constructed. Fluent Validation is a great alternative to data annotations in model validation. It allows for a greater separation of problems as well as a better control of validation rules and makes them easier to understand and test. The Lambda expression is used to verify the validity of. When you require complex validations for users’ data Fluent Validation is a great tool

Code Quality

By removing the need for annotations to data during the creation of a public class that can be used to test Your models, the FluentValidation can help create code that is simpler, easier to manage, and more reliable.

Let’s See How to Use Fluent Validation Library

Step 1: Create Employee class:

                            

                           
public class Employee
{
public Guid Id {get; set; }= Guid.NewGuid();
public string Name { get; set; }
public string Email { get; set; }
public DateTime CreatedDate { get; set; } DateTime.Now;
}

Step 2: Validated using a EmployeeDtoValidator. These classes are defined as follows:

                            

                            
                            public class EmployeeDtoValidator: AbstractValidator
                                {
                                public EmployeeDtoValidator()
                                {
                                RuleSet("name", () =>
                                {
                                RuleFor(x => x.Name). NotNull().WithMessage("name could not be null");
                                });
                                RuleSet("email", () =>
                                {
                                RuleFor(x => x.Email).NotNull().WithMessage("email could not be null");
                                });
                                }
                                }

Step 3: Configure validator class in program file.

                            builder.Services.AddScoped, EmployeeDtoValidator>();
                                builder.Services.AddValidatorsFromAssemblyContaining();

Step 4: With the manual validation approach, you’ll inject the validator into your controller and invoke it against the model.

                            

                            
For example, you might have a controller that looks like this


public class EmployeeController: Controller
{
private IValidator _validator;
public EmployeeController(IValidator validator)
{
//Inject our validator and also a DB context for storing our Employee object.
 
   _validator = validator;
 
}
public ActionResult Create()
{
return View();
}
 
[HttpPost]
public async Task Create(Employee employee)
{
var result= await _validator.ValidateAsync(employee);
if (!result.IsValid)
{
//re-render the view when validation fails. 
 
return View("Create", employee);
}
TempData["notice"] = "Employee successfully created";
 return RedirectToAction("Index");
    }
  }

SignalR

One of the main goals of modern application development is to provide users real-time information. If you’re developing an application, game or any other type of application that you’re developing, you could benefit from real-time functions. The capability of your server-side software to quickly transmit information to other clients is a sign of real-time capabilities. In this instance we will require SignalR within .Net Core. It also simplifies the process dramatically. Similar to a chatroom, SignalR automates the management of connections and lets you send messages to everyone simultaneously.

You can incorporate SignalR hubs written in C# in the .NET Core project along with your APIs and pages. Additionally, the basic approach to programming naturally integrates other advanced features in NET such as dependency injection and authorization, authentication and the ability to extend.

SignalR is an open source library that allows you to create real-time web applications within ASP.NET Core. SignalR has an API that enables server-side software to transmit messages to browsers on the client.

Benefits of SignalR:

Real-time Functionality

SignalR is a no-cost and open-source software that allows you to integrate real-time features onto the internet. By using server-side programming, data can be sent to clients in real time thanks to the capability of real-time on the web.

Networking

The ability to broadcast messages to all clients on the network at the same time. It allows communication between clients, both individually and in groups being capable of accommodating many more users.

Let’s See How to Use SignalR Library

Step 1: Install SignalR NuGet package:

ntegrate the SignalR library into your project to enable real-time communication

Step 2: Register services and CORS policy

                            

                            builder.Services.AddSignalR();
                            builder.Services.AddCors options => {
                            options.AddPolicy ("CORSPolicy", builder=> 
                            builder .AllowAnyMethod() .AllowAnyHeader() .AllowCredentials() .SetIsOriginAllowed ((hosts) => true));
                            };

Step 3: Define IMessageHubClient interface: Create an interface inside the “Hub” folder, outlining the methods for sending offers to users.

                            

                            
public interface IMessageHubClient
{
Task SendOffersToUser(List message);
}

Implement MessageHubClient class: Develop the actual SignalR hub that extends the IMessageHubClient interface. This class manages to send offers to clients.


public class MessageHubClient: Hub
{
public async Task SendOffersToUser(List message)
{
await Clients.All.SendOffersToUser(message);
}
}

Step 4: Design a controller responsible for handling offers. Inject the IHubContext to enable sending messages via SignalR.

                            

                            
public class OfferController: Controller
{
private IHubContext messageHub;
public OfferController(IHubContext_messageHub)
{
messageHub = messageHub;
}
[HttpPost]
[Route("electronic offers")]
public string Get()
{
List offers = new List();
offers.Add("28% Off on IPhone 12");
offers.Add("15% Off on HP Pavilion");
offers.Add("25% Off on Samsung Smart TV");
messageHub.Clients.All.SendOffersToUser(offers);
return "Offers sent successfully to all users!";
}
}

MailKit

MailKit is among the most popular Net Standard libraries. It is the top of MimeKit which is a .net main library that powers email clients that are cross-platform. The aim of this project is to provide robust, rich, feature-packed, and fully compatible RFC SMTP, POP3, and IMAP client network implementations.

Benefits of MailKit

Security : Simple Authentication and Security Layer (SASL) Authentication.

Proxy Support:Proxy support for SOCKS4/4a, SOCKS, and HTTP.

Let’s See How to Use MailKit Library:

Step 1

For sending an email, we must provide SMTP server information, together with the email address we wish to send emails to. The application should not be able to hardcode the details as they may alter over time and need updates. It is also easier to manage by other programmers. Below is the code in appsettings.json.

                            

                            

                                    "Logging": {
                                     "LogLevel": {
                                    "Default": "Information",
                                    "Microsoft.AspNetCore": "Warning"
                                     }
                                    },
                                    "AllowedHosts": "*",
                                    "MailSettings": {
                                    "DisplayName": "Developer Test",
                                    "From": "test@dev-test.dk",
                                    "Host": "smtp.test.email",
                                    "Password": "upPftsKAqgcFKKmXBW",
                                    "Port": "587",
                                    "UserName": "dev.test@test.email",
                                    "UseSSL": false,
                                    "UseStartTls": true
                                    }

Step 2: Create a MailSettings object file like below.

                            

                            
public class MailSettings
{
public string? DisplayName { get; set; }
public string? From { get; set; }
public string? UserName { get; set; }
public string? Password { get; set; }
public string? Host { get; set; }
public int Port { get; set; }
public bool UseSSL { get; set; }
public string UseStartTls (get; set;) }

Step 3: Create a new file named MailData.cs with the following properties inside.

                            

                           
                            public class MailData
{
// Receiver
public List To { get; }
public List Bcc { get; }
public List Cc { get; }
// Sender
public string? From { get; }
public string? DisplayName { get; }
public string? ReplyTo ( get;) }
public string? ReplyToName { get; }
// Content
public string Subject { get; }
public string? Body { get; }
public MailData(List to, string subject, string? body = null, string? from = null, string? displayName = null, string? replyTo = null, string? replyToName = null, List? bcc = null, List? cc = null)
{
// Receiver
To = to;
Bcc=bcc?? new List();
Cc = cc ?? new List();
// Sender
From = from;
DisplayName = displayName;
ReplyToName = replyToName;
ReplyTo = replyTo;
// Content
Subject = subject;
Body = body;
}

Step 4: Create a new folder named Services at the root of your project along with two new files inside named ImailService.cs and MailService.cs.

                            

                            
                            public class MailService: IMailService
{
private readonly MailSettings _settings;
public MailService(IOptions settings)
{
    _settings = settings.Value;
}
public async Task SendAsync(MailData mailData, CancellationToken ct = default)
{
  try
{
// Initialize a new instance of the Minekit. MinaMessage class
var nail = new MineMessage();
#region Sender / Receiver
// sender
mail.From.Add(new MailboxAddress(_settings.DisplayName, mailData. From ?? _settings From));
mail.Sender = new MailboxAddress(mailData.DisplayName ?? _settings.DisplayName, mailData .From ?? _settings.From);
// Receiver
foreach (string mailAddress in mailData.To)
mail.To.Add(MailboxAddress, Parse(mailAddress));
// Set Reply to if specified in mail data 
 
 
if!string.IsNullOrEmpty(mailData.ReplyTo)
mail. ReplyTo.Add(new MailboxAddress(mailData.ReplyToNane, mailData.ReplyTo));
// BCC
// Check if a BCC was supplied in the request
if (mailData.Bcc != null)
{
// get only addresses where value is not null or with whitespace. x value of address
 
foreach (string mailAddress in mailData.Bcc. Where(x=>!string.IsNullOrWhiteSpace(x))) mail.Bcc.Add(MailboxAddress.Parse(mailAddress.Trim()));
}
// Check if a CC address was supplied in the request
if (mailData.Cc != null)
{
foreach (string mailAddress in mailData.Cc.Where(x=> !string.IsNullOrWhiteSpace(x))) mail.Cc.Add(MailboxAddress.Parse(mailAddress.Trim()));
}
#endregion



#region Content
// Add Content to Mine Message
 
var body=new BodyBuilder();
mail.Subject mailData.Subject;
body.HtmlBody = mailData.Body;
mail. Body = body.ToMessageBody();
#endregion
#regian Send Mail
using var smtp = new SmtpClient();
if (_settings.UseSSL)
{
await smtp.ConnectAsync(_settings.Host, _settings.Port, SecureSocketOptions.SsLOnConnect, ct);
else if (_settings.UseStartTls)
{
await smtp.ConnectAsync(_settings.Host, _settings.Port, SecureSocketOptions.StartTls, ct);
}
await smtp.AuthenticateAsync(_settings. UserNane, _settings.Password, ct);
await smtp. SendAsync(mail, ct);
await smtp.DisconnectAsync(true, ct);
#endregion
return true;
}
catch (Exception)
{
return false;
}
}
}

Step 5: Configure MailSettings and MailService in the program.cs

                            

                            
builder.Services.Configure (builder.Configuration .GetSection(nameof (MailSettings)));
builder .Services .AddTransient();

Step 6: Add a new MailController to send emails

                            

                           
public class MailController: Controller

private readonly MailService _mail;
public MailController(IMailService mail)
{
_mail = mail;
}
[HttpPost("sendmail")]
public async Task SendMailAsync(MailData mailData)
{
bool result = await _mail.SendAsync(mailData, new CancellationToken());
if (result)
{
return StatusCode(StatusCodes.Status2000K, "Mail has successfully been sent.");
else
{
return StatusCode(StatusCodes.Status500Internal ServerError, "An error occurred. The Mail could not be sent.");
}
}
}

Autocomplete

Autocomplete is an ASP.NET core library that enables desktop as well as online and cloud applications to auto-complete features such as text fields or domains.

Benefits of Autocomplete

Autofill search

The autofill search feature in the ASP.NET Core, AutoComplete control lets the user quickly and easily look for objects by filling in the word they type in accordance with the text recommendation.

UI customization

Using templates, you may change how each recommendation looks when it’s shown.

Responsive UI

Adaptive user interface (UI) created specifically for mobile devices that respond to touch

Let’s See How to Use Autocomplete Library

The jQuery AutoComplete plugin has been applied to the TextBox and the URL of the plugin is set to the AutoComplete Action method. 

                            

                            
                            $(function (){
                                $("#txtEmployee").autocomplete(
                                source: function (request, response) {
                                $.ajax(
                                url: ‘/Employee/GetEmployees/’,
                                data: "prefix": request.tern ),
                                type: "POST",
                                success: function (data){

.NET libraries are collections of reusable code components that provide common functionality for .NET developers. They contain pre-written code for tasks such as file I/O, data manipulation, networking, and more, allowing developers to save time and effort by leveraging existing solutions.
Some popular .NET libraries include:
  • Newtonsoft.Json (Json.NET)
  • Entity Framework Core
  • Dapper
  • NUnit
  • Moq
  • AutoMapper
  • Serilog
  • RestSharp
  • FluentValidation
  • Polly
Newtonsoft.Json, commonly known as Json.NET, is a popular library for working with JSON data in .NET applications. It provides a simple and flexible API for serializing and deserializing JSON objects, making it easy to integrate JSON data into .NET applications.
Entity Framework Core is an object-relational mapping (ORM) framework for .NET applications. It simplifies data access by providing a set of APIs for working with relational databases using object-oriented principles. Entity Framework Core supports various database providers and can be used to perform CRUD operations, manage relationships, and more.
Dapper is a lightweight micro-ORM library for .NET applications. It provides a fast and efficient way to execute SQL queries and map query results to .NET objects. Dapper is known for its simplicity and performance and is often used in projects where raw SQL execution is preferred over ORM-based solutions
NUnit is a popular unit testing framework for .NET applications. It provides a set of attributes, assertions, and test runners for writing and executing unit tests in C#, VB.NET, and other .NET languages. NUnit supports various test runners and integrates seamlessly with popular IDEs such as Visual Studio.
Moq is a mocking library for .NET applications. It allows developers to create mock objects and define behavior for method calls, property accesses, and more during unit testing. Moq simplifies the process of mocking dependencies and writing testable code by providing a fluent and expressive API.
AutoMapper is a mapping library for .NET applications. It simplifies the process of mapping data between objects by automatically configuring mappings based on convention or explicit configuration. AutoMapper is commonly used in projects where object-to-object mapping is a frequent requirement, such as data transfer objects (DTOs) and view models.
Serilog is a logging library for .NET applications. It provides a flexible and extensible logging framework with support for structured logging, log filtering, and log enrichment. Serilog is known for its ease of use and powerful features, making it a popular choice for logging in .NET projects.
RestSharp is a simple REST and HTTP API client library for .NET applications. It provides a fluent and intuitive API for making HTTP requests and handling responses, including support for authentication, serialization, and error handling.
