Adding Swagger to a .Net core application

If you have used Swagger with a website to document your API, then you know it has some nice features for testing your API as well as viewing the structure and documentation.

This is brief walkthrough of setting up Swagger.

First install the Swashbuckle nuget package.

In the startup.cs file of your .Net core web app, change ConfigureServices to have the following.

public IServiceProvider ConfigureServices(IServiceCollection services)


            // Add framework services.



            services.AddSwaggerGen(c =>


                c.SwaggerDoc(“v1”, new Info { Title = “MyAPI”, Version = “v1” });


            services.ConfigureSwaggerGen(c =>





            return ConfigureIoC(services);


And add this:

private string GetXmlCommentsPath(ApplicationEnvironment appEnvironment)


            return Path.Combine(appEnvironment.ApplicationBasePath, "SolutionName.Project.ProjectAPI.xml");

//The above is coming from the .Net core project properties, build tab. // You need to check the box to create the XML documentation and use the file name from there.
