The authenticate request model defines the parameters for incoming requests to the /users/authenticate route, it is attached to the route as the parameter to the Authenticate action method of the users controller. When an HTTP POST request is received by the route, the data from the body is bound to an instance of the AuthenticateRequest class, validated and passed to the method. The custom [Authorize] attribute is added to controller classes or action methods that require the user to be authenticated.

It is now considered deprecated technology and Microsoft recommends using ASP.NET for developing new applications. In this Web Pages tutorial you will learn how to combine HTML, CSS, JavaScript and server code, using server code written in VB or C# . In addition, Web Pages applications are easily extendable with programmable helpers for databases, videos, graphics, social networking and more. Web Pages is one of many programming models for creating ASP.NET web sites and web applications. Authorization is performed by the OnAuthorization method which checks if there is an authenticated user attached to the current request (context.HttpContext.Items["User"]).

For more info on the C# project file see .NET + MSBuild - C# Project File (.csproj) in a Nutshell. Run your ASP.NET Core Web API project, and you can use Postman or any other API testing tool to test the CRUD operations on the CSharpCornerArticle model. In the Controllers folder, create a controller to handle CRUD operations. This command will create a new ASP.NET Core Web API project named CSharpCornerApi.

ASP.NET is open source and a subset of the .NET Framework and successor of the classic ASP(Active Server Pages). With version 1.0 of the .NET Framework, it was first released in January 2002. So a question comes to mind that which technology we were using before the year 2002 for developing web applications and what is asp.net c# services? ASP.NET is an open-source,[2] server-side web-application framework designed for web development to produce dynamic web pages. It was developed by Microsoft to allow programmers to build dynamic web sites, applications and services. The name stands for Active Server Pages Network Enabled Technologies.

All of these files are text files, and therefore human readable and writeable. It is not simply the next-generation of ASP; in fact, it is a completely re-engineered and enhanced technology that offers much, much more than traditional ASP and can increase productivity significantly. Both technologies enable computer code to be executed by an Internet server. Connect and share knowledge within a single location that is structured and easy to search.


Controller methods/routes are secure by default with the [Authorize] attribute on the class. The Authenticate method is decorated with the [AllowAnonymous] attribute which overrides the class-level [Authorize] attribute to make it publicly accessible. The WebApplication class handles app startup, lifetime management, web server configuration and more. The logic for allowing public access is located in the custom authorize attribute below, authorization is skipped if the action method is decorated with [AllowAnonymous]. ASP.NET is built on the CLR(Common Language Runtime) which allows the programmers to execute its code using any .NET language(C#, VB etc.).

The user entity class represents the data for a user in the application. Entity classes are used to pass data between different parts of the application (e.g. between services and controllers) and can be used to return http response data from controller action methods. If multiple types of entities or other custom data is required to be returned from a controller method then a custom model class should be created in the Models folder for the response. The authorization code that checks for the user object is located in the custom authorize attribute above.

You will also learn how to extend your web pages with programmable Web Helpers. Other than coding I'm attempting a big lap of Australia by motorcycle with my wife Tina, you can follow the adventure on YouTube & TinaAndJason.com.au. Search fiverr to find help quickly from experienced .NET freelance developers.

  • The .NET users controller defines and handles all routes / endpoints for the api that relate to users, this includes authentication and standard CRUD operations.
  • The ImplicitUsings feature is enabled which tells the compiler to auto generate a set of global using directives based on the project type, removing the need to include a lot of common using statements.
  • Because ASP.NET code is executed on the server, you cannot view the code in your browser.
  • For more info on the C# project file see .NET + MSBuild - C# Project File (.csproj) in a Nutshell.

Since ASP is in such wide use, however, Microsoft ensured that ASP scripts execute without modification on a machine with the .NET Framework (the ASP engine, ASP.DLL, is not modified when installing the .NET Framework). Thus, IIS can house both ASP and ASP.NET scripts on the same machine. Because it has evolved from ASP, ASP.NET looks very similar to its predecessor-but only at first sight.

Native ASP.NET files by default have the extension .aspx (which is, of course, an extension to .asp) or .ascx. I have seen many tutorials on ASP.NET but most of them starts with coding and writing your first ASP.NET program. It was first released in January 2002 with version 1.0 of the .NET Framework and is the successor to Microsoft's Active Server Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write ASP.NET code using any supported .NET language.

You can use directives to specify optional settings used by the page compiler when processing ASP.NET files. One example is the language directive at the beginning of a page defining the default programming language. C# is a CLS programming language designed for the .NET framework.
