No API descriptions with Swashbuckle 5.0 and OWIN

I’ve read the documentation on Swashbuckle 5.0 and the only thing we have to do is to enable Swagger and SwaggerUI via Swashbuckle.Core. The /swagger/ui/index shows up but with no descriptions…

Here is my Startup.cs :

public partial class Startup
  {
    public void Configuration(IAppBuilder app)
    {
      ConfigureAuth(app);
      ConfigureWebApi(app);
      RegisterSwagger(app);
    }
  }

Here is my Startup.SwaggerConfig.cs :

public partial class Startup
    {
      public static void RegisterSwagger(IAppBuilder app)
      {
          GlobalConfiguration.Configuration 
            .EnableSwagger(c =>
                  {
                      c.SingleApiVersion("v1", "MyAPI");
                      c.IncludeXmlComments(GetXmlCommentsPath());
                  })
              .EnableSwaggerUi();
      }

      protected static string GetXmlCommentsPath()
      {
        return System.String.Format(@"{0}\bin\MyAPI.XML", System.AppDomain.CurrentDomain.BaseDirectory);
      }
    }

Did I miss something? I’ve make some research on that issue and it seems that with Swashbuckle 4.0 there was an Swashbuckle.Bootstrapper.Init(config); Is it replaced with something else?

Ok, I have managed to configure Swagger inside OWIN Startup class:

public void Configuration(IAppBuilder app)
    {
        HttpConfiguration config = new HttpConfiguration();

        // Swagger
        SwaggerConfig.Register(config);

        // Authentication token
        ConfigureOAuth(app);

        // SignalR configuration
        ConfigureSignalR(app);

        // Register routes
        WebApiConfig.Register(config);

        // Allow cross-domain requests
        app.UseCors(CorsOptions.AllowAll);

        app.UseWebApi(config);
    }

And in SwaggerConfig,cs:

using Swashbuckle.Application;
using System.Web.Http;

namespace Name.API 
{
     public class SwaggerConfig
     {
          public static void Register(HttpConfiguration config)
          {
                config.EnableSwagger(c =>
                {
                    c.SingleApiVersion("v1", "Name.API");   
                })
            .EnableSwaggerUi(c =>
                {
                });
         }
     }
}

Thanks @corneliu-serediuc this handled my problem. The actual nuget package uses [assembly: PreApplicationStartMethod(typeof(SwaggerConfig), “Register”)] which only works when the project isn`t based on OWIN. If you comment this attribute out, and call the Register from the Startup.cs the methods get discovered just fine… Thanks!
