This ASP.NET Core MVC framework provides us full control over the markup. It also supports for Test-Driven Development and also uses the latest web standards such as HTML 5, Bootstrap, Jquery, etc. In ASP.NET Core MVC Application, a Controller is a .cs (for C# language) file which has some methods called Action Methods. When a request comes on the controller, it is the controller’s action method going to handle those requests.
It also allows you to develop a web application that can run on Mac OS and Linux. Many companies have already started building their new applications with ASP.NET Core. And they’re asking their new interviewees if they are familiar with .NET Core. So, if you are looking for a job and have some .NET experience, I suggest you learn ASP .NET Core to stay ahead of your competition. In the MVC design pattern, the Model component also contains the required logic in order to retrieve the data from a database. Once the model is created by the controller, then the controller selects a view to render the domain data or model data.
ASP.NET Core MVC – Model Binding
The Model in an MVC application represents the state of the application and any business logic or operations it should perform. Business logic should be encapsulated in the model, along with any implementation logic for persisting the state of the application. Strongly-typed views typically use ViewModel types designed to contain the data to display on that view. The controller creates and populates these ViewModel instances from the model. The controller is the MVC design pattern component that handles the incoming request.
It’s important to note that the .NET ecosystem continues to evolve, with new features and improvements regularly added in subsequent versions beyond .NET 6. ASP.NET Core (.NET) is a free, open-source, and cloud-optimized framework that can run on Windows, Linux, or macOS. The framework is a complete rewrite from scratch to make it open-source, modular, and cross-platform. These ASP.NET Core Tutorials are designed for Beginners and Professional Developers who want to learn ASP.NET Core step by step. The course starts with teaching you the Model-View-Controller design pattern and how you can use it to organize and develop your web application. You’ll then dive into JSON web APIs which allow communication between your back-end ASP.NET application and front-end web/mobile application.
Add Model
In order to handle the request, the controller components do several things, as follows. The controller component creates the model that is required by a view. The model is the component in the MVC design pattern which basically contains classes that are used to store the domain data or, you can say, business data. Yes, he really starts from ground zero and then writes code and explains every single line of it. Talking about social proof, this course is trusted by more than 29,000 students, and it has, on average, 3.6 ratings from close to 7,000 participants, which is phenomenal.

Let us create one employee and click the Create button, as shown in the image below. Here, I am going to Scaffold Controllers and Views, which will automatically generate the Actions and views using Entity framework core for us to perform the CRUD Operations. Later, we will modify the auto-generated actions and views as per our requirements. Please follow the below steps to Scaffold Controllers and View. In this course, you will learn to make Model-View-Controller (MVC) applications with ASP.NET Core.

Apart from Mosh Hamdani, another instructor I found on .NET technologies is Scott Allen on Pluralsight. This course covers the fundamentals of what you need to know to start building your first ASP.NET Core application with the MVC framework. You’ll learn topics like middleware, tag helpers, view components, supporting SQL Server using the Entity Framework, and user registration with the Identity Framework. You’ll also see novel techniques for working with front-end frameworks like Bootstrap and JavaScript libraries like jQuery.
Once the view generates the HTML, that HTML is sent to the client over the network who initially made the request. It includes the core features required to run a basic .NET Core app. Other features are provided as NuGet Packages, which you can add to your application ASP.NET Core 3.1 MVC Lessons as needed. In this way, the .NET Core application speeds up the performance, reduces the memory footprint, and becomes easy to maintain. It was designed to build modern, high-performance, and scalable applications that could run on Windows, macOS, and Linux.

Now, click the Delete button as shown in the above image to Delete the Employee from the database. Once you click the Delete button, it will open the following Delete View. Now, it should display the Department Name in the dropdown list. Let us modify the Employee Department to IT and Position to DBA and click on the Save button, as shown in the image below.
Controller methods, such as the Index method above, generally return an IActionResult (or a class derived from ActionResult), not a type like string. ASPNETCORE_ENVIRONMENT when ConfigureWebHostDefaults is called. The default ASP.NET Core web app templates call ConfigureWebHostDefaults. The ASPNETCORE_ENVIRONMENT value overrides DOTNET_ENVIRONMENT.
