There is nothing like a page in an ASP.NET for .NET Core MVC application and it also doesn’t have something that refers directly to a page when you define a route in the URL. The closest thing to a page in an application for ASP.NET for Dot net online training Core MVC is known as a view.
As you know, all incoming browser requests in the ASP.NET MVC framework are managed by the controller and these requests are mapped to the controller’s behavior.
A controller action might return a view or some other type of action, such as redirecting to another controller action, may also be performed.
The most common method for generating HTML with the MVC framework is to use ASP.NET MVC’s Razor view engine.
To use this view engine, a ViewResult object is created by a controller action, and a ViewResult may carry the name of the Razor view that we want to use.
Core for ASP.NET
Supports Various Platforms:
On Windows, Linux, and Mac, ASP.NET Core applications can be installed. And you don’t need to create multiple apps using different frameworks for different platforms.
Fast:
For browser-server communication, ASP.NET Core no longer relies on System. Web.dll. ASP .NET online training
Core makes it possible for us to provide the packages we need for our application. This reduces the pipeline of requests and increases performance and scalability.
IoC Container:
This includes the built-in automated dependency injection IoC container that makes it maintainable and testable.
Modern UI Frameworks Integration:
It enables modern UI frameworks such as AngularJS, ReactJS, Ember, Bootstrap, etc. to be used and managed using Bower (a package manager for the web).
Hosting:
ASP.NET The core web application can be hosted on different web server platforms, such as IIS, Apache, etc. As a standard .NET application, it is not based only on IIS.
Sharing code:
Helps you to build a library of classes that can be used with other .NET frameworks, such as .NET Framework 4.x or Mono. A single codebase can also be exchanged through frameworks.
Side-by-Side Software Versioning:
ASP.NET Core runs on .NET Core, which supports several program versions running concurrently.
Smaller Implementation Footprint:
The program ASP.NET Core runs on .NET Core, which is smaller than the .NET System as a whole. So, there will be a smaller deployment size for the program that uses only a portion of .NET CoreFX. This decreases the footprint for deployment.
View Outcome
The view is a file on the file system, and the View Result can also hold the view along with the model object, and the view can use the model object when HTML is generated.
When the MVC framework sees that a View Result is generated by the controller operation, the framework can find the view on the file system, execute the view that generates HTML, and it is this HTML that is sent back to the client by the framework.
Example
To understand how this works in our application, let us now take a simple example by modifying the implementation of the Home Controller Index method as shown in the following program.
FirstAppDemo.Models used;
Microsoft.AspNet.MVC usage;
Applying System;
System.Collections.Generic is used;
Usage of System. Linq;
System.Threading.Tasks are used;
FirstAppdemo.Controllers namespace {
HomeController Public Class: Controller {
ViewResult Public Index() { {
Employee var = new Employee { ID = 1, Name = “Mark Upston”};
View(); returns;
}
}
}
Instead of generating an ObjectResult within the HomeController, let us only return what the View() method returns. An ObjectResult is not returned by the View process. This produces a new ViewResult, so we’ll also adjust the Index method’s return form to ViewResult. Here, the View method accepts certain parameters. This method will be invoked without any other parameters. Let us save your browser file and refresh it.
Object Result
This is because the system for the MVC must go out and find the view, but right now there is no view.
Views are files that have a *.cshtml extension by default in a C# ASP.NET project and the views follow a particular convention. By default, all views live in the project’s Views folder.
If you don’t offer any additional details, ASP.NET online training india
MVC will derive the view location and the view file name.
The first place that the MVC framework would search for that view is within the Views folder if we need to make a view from the Home Controller’s Index action.
It will go to the Home folder and then search for a file named Index. cshtml, since we’re in the Index action, the file name begins with Index.
The MVC framework will also look within the Shared folder and you can use the views you put within the Shared folder anywhere in the application.
Let us build this Index. CSS HTML file in the correct location for our view results to function correctly. But we need to first add a folder to our project that will hold all of our views, and call it Views. We’ll add another folder within the Views folder for views that are connected to our Home Controller and call that folder Home. Right-click the Home folder, then choose Add ⁇ New Item.
Select Add New Item Select
Select the MVC View Page from the left pane, enter index. cshtml in the name section, and then press the Add button.
Let us add the following code to a file called index.cshtml.
