Asp net web api help page does not show any description

Introduction

ASP.NET is a popular programming language used for web applications. One of its key features is the ability to create Web APIs, which allow developers to their application's functionality as a set of HTTP services. These APIs can be by other applications or clients, making it easier to integrate systems together.

The Problem

One common issue that developers face when working with ASP.NET Web API is that the help page, which is automatically by the framework, does not show any description for the API methods. This can make it difficult for other developers to understand how to use the API and what each method does.

The Solution

To solve this problem, we need to provide a description for each API method so that it can be displayed on the help page. Fortunately, ASP.NET Web API provides a way to add these using XML comments.

Step 1: Enable XML Documentation

The first step is to enable XML documentation in your ASP.NET Web API project. To do this, open the project properties and go to the “” tab. Check the “XML documentation file” option and specify a file name for the XML documentation file. This file will the XML comments for your API methods.


// Enable XML documentation
/// 
/// This is a sample API method.
/// 
/// 
/// The item with the specified ID
public IHttpActionResult Get(int id)
{
    //  goes here
}

Step 2: Add XML Comments

Once XML documentation is enabled, you can add XML comments to your API methods. These comments should provide a brief description of the method, as well as any parameters and return values.


// Add XML comments
/// 
/// This is a sample API method.
/// 
/// 
/// The item with the specified ID
public IHttpActionResult Get(int id)
{
    // Implementation goes here
}

Step 3: Generate Help Page

After adding XML comments to your API methods, you need to generate the help page again. To do this, build your ASP.NET Web API project and to the help page URL. You should now see the descriptions for each API method.

Conclusion

By following these steps, you can solve the problem of the ASP.NET Web API help page not showing any description. Adding XML comments to your API methods allows other developers to understand how to use your API and what each method does. This improves the overall usability and documentation of your web application.
