Auto Generate Documentation for ASP.net WebAPI

Auto Generate Documentation for ASP.net WebAPI

Auto-generating documentation for an ASP.NET Web API project can be done using a tool called Swagger. Swagger is an open-source framework that provides a standardized way to describe and document RESTful APIs.

Here are the steps to auto-generate documentation for an ASP.NET Web API using Swagger:

  1. Install the Swashbuckle NuGet package: Swashbuckle is an extension of Swagger for ASP.NET Web API. To install Swashbuckle, open the Package Manager Console and run the following command:

    Install-Package Swashbuckle

  2. Configure Swagger: In the Startup.cs file, add the following code to the ConfigureServices method:

    services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" }); });

    This configures Swagger to generate documentation for your API with a title of "My API" and a version of "v1".

  3. Enable the Swagger middleware: In the Startup.cs file, add the following code to the Configure method:

    app.UseSwagger(); app.UseSwaggerUI(c => { c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1"); });

    This enables the Swagger middleware and adds a UI for exploring the API documentation. The SwaggerEndpoint method specifies the URL of the Swagger JSON file that Swagger generates.

  4. Generate Swagger documentation: Run your ASP.NET Web API project and navigate to http://localhost:<port>/swagger/v1/swagger.json. This will generate the Swagger JSON file that describes your API.

  5. View Swagger UI: Navigate to http://localhost:<port>/swagger to view the Swagger UI for your API. The Swagger UI provides a user-friendly interface for exploring the API documentation.

By following these steps, you can auto-generate documentation for an ASP.NET Web API project using Swagger.
