Interesting new features of the ASP.NET Core MVC
ASP.NET core is a lean and developer friendly framework to build rich web applications and APIs. With ASP.NET Core MVC, the web apps development can be carried out using the MVC architectural pattern. To take a step back, the Model-View-Controller (MVC) pattern ensures adherence to good coding and testing practices for better and faster product development. Using this approach, ASP.NET core can be used to create dynamic sites that enables clear separation of concerns.
Check out the top features in ASP.NET Core MVC that you ought to know as a developer –
- Routing
This framework supports routing and allows developers to create apps that have searchable URLs. Be it link building or search engine optimization, your digital marketing objectives can be served well with the custom URL naming patterns made possible through routing. This can be achieved in two ways - Convention based
Developers can set a global URL format definition. In case of an incoming request the engine assesses the URL, matches it to one of the global URL formats, and then calls the related controller’s method. For example:
routes.MapRoute(name: "Default", template: "{controller=Home}/{action=Index}/{id?}"); - Attribute based
If attributes accompany your controllers and actions, then this is an attribute based routing. For example
[Route("api/[controller]")]
public class ProductsController : Controller
{
[HttpGet("{id}")]
public IActionResult GetProduct(int id)
{
...
}
} - Model Binding
Converting the client request data (form values, route data, query string parameters, HTTP headers) into controller-readable objects is made possible with model binding feature in the framework. Be it strings, float, numbers, or complex types, various parameters can be handled easily with the model binding feature. This eliminates the need to determine the incoming request data, as this is already present as parameters to its action methods.
public async Task Login(LoginViewModel model, string returnUrl = null) { ... } - Dependency Injection
With default support for Dependency Injection the framework, a .net development company India can separate the logic of creating dependent objects in the MVC architecture.
@inject SomeService ServiceName
<!DOCTYPE html>
<html lang="en">
<head>
<title>@ServiceName.GetTitle</title>
</head>
<body>
<h1>@ServiceName.GetTitle</h1>
</body>
</html> - Model Validation
Getting the data annotation validation attributes on the model object ensures validation on the client side before it is posted to the server. Alternatively it is checked on the server side before calling upon the controller action.
using System.ComponentModel.DataAnnotations;
public class LoginViewModel
{
[Required]
[EmailAddress]
public string Email { get; set; }
[DataType(DataType.Password)]
public string Password { get; set; }
public bool RememberMe { get; set; }
} - Areas
A big web app can be easily split into smaller manageable groups using the Areas method. Every Area acts like a distinct part of the application with its own models, views, and controllers. Areas come in useful to tackle numerous controllers and ensure a cleaner code. - Filters
Filters are custom classes that help an expert in .net development services India to perform logic either prior to calling an action method or post the execution of an action method. With this issues like exception handling and authorization can be easily handled. See an example of the ‘Authorize’ filter
[Authorize]
public class AccountController : Controller
{ - Web APIs
A smart developer skilled in custom .net development india knows that ASP.NET Core MVC can be used not only for creating websites. It can also be used to web APIs to expand the reach of your digital presence to mediums like mobile devices and browsers. The ability to format data as JSON/XML, use of custom formatters, and HTTP content negotiation makes it a good choice for creating web APIs - View Components
With this framework, rendering logic can be packaged and reused at multiple places across the application. This is made possible with the ‘View components’ feature. - Tag Helpers
With tag helpers, server side binding can be achieved without server-side coding. Custom tags can be defined to extend functionality or modify the action of in-built tags. For example the LinkTagHelper can add al ink to the AccountsController’s ‘Login’ action
<p>
Thank you for confirming your email.
Please <a asp-controller="Account" asp-action="Login">Click here to Log in</a>.
</p> - Razor View engine
Razor is a popular markup language used by .Net MVC Development professionals to define views using embedded C# code. It assists in dynamic web content on the server.
When you hire Asp.net core Developers, testing them on these new features of ASP.NET Core MVC can be a great assessment of his/her programming and development caliber.
