Learn how to build web apps using ASP NET Core 3.1

These ASP.NET Core tutorials will help you to build rich data-driven web applications. At the end of these ASP.NET Core Tutorials, you will be better positioned to perform all the CRUD (i.e., Create, Read, Update, and Delete) operations using the SQL Server database. You will learn ASP.NET Core basics, ASP.NET Core Razor Pages, ASP.NET Core MVC, Blazor, Entity Framework Core, and ASP.NET Core Web API. Think of this “Pages” folder as a virtual root of your web application. Razor Pages is the default for building server-side web applications in ASP.NET Core. Components within the underlying MVC framework still have their uses such as using controllers for building RESTful APIs. Razor Pages is included within .NET Core from version 2.0 onwards, which is available as a free download as either an SDK (Software Development Kit) or a Runtime.

This site is dedicated to helping developers who want to use the ASP.NET Razor Pages web development framework to build web applications. When using the Async alternatives for each handler methods, you should return a Task object (or void for the non-async version). To include a return value, you should return a Task (or IActionResult for the non-async version). To use the Model’s properties, you can use the syntax Model.Property to refer to each property by name. Instead of using the name of the model, you have to use the actual word “Model” in your Razor Page code. Note that [BindProperty] allows you to bind properties for HTTP POST requests by default. RedirectToPage method is a helper method that comes with PageModel and helps to eliminate the need to write up a new instance of an action result and simplify the code. In this course you will first learn about the history and basics of ASP.NET Core. Then you will learn how to build a small book list application with CRUD operations. You will learn how to use the Entity Framework for integration with a database with ASP.NET Core Razor Pages. Then create a Bindable property called Id which also should support Get within the same EmployeeModel class as shown in the below image.

1.5 Using your existing knowledge

You can even use your Razor knowledge to work on Blazor fullstack web development. Right-click on your project root directory and then add a new class file with the name Employees.cs and then copy and paste the following code into it. You can still choose to use ASP.NET Core MVC to build your ASP.NET Core web applications. If you are ASP.NET Core 3.1 Razor Lessons porting an existing .NET Framework MVC application (MVC5 or earlier) to .NET Core, it may well be quicker or easier to keep with the MVC framework. However, Razor Pages removes a lot of the unnecessary ceremony that comes with the ASP.NET implementation of MVC and is a simpler, and therefore more maintainable development experience. Here, the value for SearchString is used by the OnGetAsync() method in the Index.cshtml.cs class for ResourceLists. In the code snippet below, you can see that a LINQ Query filters the movies by a subset of movies where the Title contains the SearchString value. The above snippet shows 3 different options for an id parameter, an optional id parameter and an integer-enforced id parameter. In the C# model code, a property named id can be automatically bound to the page parameter by using the aforementioned [BindProperty] attribute.

Page Parameters

To keep things simple, we are using the in-memory collection as the data source. In this article, I am going to show you how to develop ASP.NET Core Razor Pages Application step-by-step with an example. It is a server-side rendered, page-based model for building web UI with ASP.NET core.

• In this example, we create a new razor page “Get Employee” which displays the First Name of the employee for the given Id.
• When using the Async alternatives for each handler methods, you should return a Task object (or void for the non-async version).
• The SDK is installed for you when you install Visual Studio 2017 Update 3 or later.
• Other features are provided as NuGet Packages, which you can add to your application as needed.

Create a constructor which takes a parameter “List” within the “EmployeeModel” class. Once you click on the Add button, it will create Employee.cshtml page within the Pages folder as shown in the below image. Once you add the above code within the _Layout.cshtml file, your code should look as shown below. Sample application to understand how the verb Get() works in razor pages. In this example, we create a new razor page “Get Employee” which displays the First Name of the employee for the given Id. Microsoft continued encouraging developers to migrate from .NET Framework to .NET Core and the subsequent .NET 5+ versions to take advantage of the benefits mentioned above. In the sample project, browsing to the ResourceLists page with the search string “videos” includes any search results that include the term “videos”, as shown in the following screenshot. Page parameters can be included with the @page directive at the top of the page. To indicate that a parameter is optional, you may include a trailing ?
