By convention, all Razor Pages should be in a root-level “Pages” folder. These are key features introduced in each version of .NET Core and the subsequent unified .NET platform. 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. 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.

In both cases, learning C# as a language and ASP.NET Core as a framework will tick those boxes. If you are a seasoned developer, the Razor Pages framework is likely to add to your skillset with the minimum amount of effort. This site is dedicated to helping developers who want to use the ASP.NET Razor Pages web development framework to build web applications.

ASP.NET Core Tutorials For Beginners and Professionals

This is the second of a new series of posts on ASP .NET Core 3.1 for 2020. In this series, we’ll cover 26 topics over a span of 26 weeks from January through June 2020, titled ASP .NET Core A-Z! To differentiate from the 2019 series, the 2020 series will mostly focus on a growing single codebase (NetLearner!) instead of new unrelated code snippets week. 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.

Even numbered releases are LTS releases with free support and patches for three years. Odd-numbered releases are STS releases with free support and patches for 18 months. Razor Pages were introduced in ASP .NET Core v2.0, and briefly covered in my 2018 series, and with more detail in my 2019 A-Z series. To complement this updated post in 2020, you may also refer to a previous posts in this series to learn more about Forms and Fields (specifically the Razor Pages section). First of all, make sure that the Index page is within the same controller as the OnGetAsync method. If not, I would recommend to use the RedirectToAction(“Action”, “Controller”);.

ASP.NET Core MVC – File Handling

The SDK includes the runtime and command line tools for creating .NET Core applications. The SDK is installed for you when you install Visual Studio 2017 Update 3 or later. The Runtime-only installation is intended for use on machines where no development takes place. This was created by starting ASP.NET Core 3.1 Razor Lessons with the Core 3.1 Razor Pages Template in VS2019 and then updating it to view/edit data from the shared NetLearner database. Parameters defined in the C# code can be used similar to HTML attributes when using the component, including RenderFragments can be used like nested HTML elements.

For individual developer’s local development (in an accompanying appsettings.Local.json config file). Connect and share knowledge within a single location that is structured and easy to search. These methods can be overridden and defined in the @code section (formerly @functions section) of a .razor page, e.g.

R is for Razor Pages

These can be defined in sub-components such as ConfirmDialog.razor and ResourceDetail.razor that are inside the LearningResources.razor component. This “app” (formerly defined in a static “index.html” in pre-release versions) is now defined in the aforementioned “_Host.cshtml” page. Note that the Configure() method takes in an app object of type IApplicationBuilder, similar to the IApplicationBuilder we see in regular ASP .NET Core web apps. A call to MapFallBackToPage() indicates the “/_Host” root page, which is defined in the _Host.cshtml page in the Pages subfolder. ASP.NET Core (.NET) is a free, open-source, and cloud-optimized framework that can run on Windows, Linux, or macOS.

ASP.NET Core 3.1 Razor Lessons

Built on top of MVC in ASP .NET Core, Razor Pages allows you to simplify the way you organize and code your web apps. Your Razor Pages may coexist along with a backend Web API and/or traditional MVC views backed by controllers. Razor Pages are typically backed by a corresponding .cs class file, which represents a Model for the Page with Model Properties and Action Methods that represent HTTP Verbs. You can even use your Razor knowledge to work on Blazor fullstack web development.

Instead of using the name of the model, you have to use the actual word “Model” in your Razor Page code. This may come in handy when passing in QueryString parameters to be consumed by your Razor Page. Parameters are optional and are part of the route used to access your Razor Pages. Note that [BindProperty] allows you to bind properties for HTTP POST requests by default.

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.

The App component is defined in App.razor, at the root of the Blazor web app project. This App component contains nested authentication-enabled components, that make use of the MainLayout to display the single-page web application in a browser. If the user-requested routedata is found, the requested page (or root page) is displayed.
