Swagger UI not showing controllers/routes for ASP.NET API - asp.net

Question

I'm trying to setup Swagger for my API, I have the interface at http://localhost/myAPI/swagger, but my controllers/routes are not displayed.
I'm using .net-framework, not .net-core
Startup:
public class WebApiApplication : HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
}
Route config :
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { id = UrlParameter.Optional }
);
}
}
Controller:
[RoutePrefix("v1/controller")]
public class TestController : ApiController
{
[Route("client")]
[HttpPut]
public HttpResponseMessage CreateClient([FromUri] string id)
{
return new HttpResponseMessage(HttpStatusCode.OK);
}
[Route("portfolio")]
[HttpPost]
public IResponseItem<int> CreatePortfolio([FromUri] string id)
{
return new ResponseItem<int>
{
StatusCode = HttpStatusCode.Created,
Message = "Portfolio successfully created",
Item = 12
};
}
}
Swagger config :
public class SwaggerConfig
{
public static void Register()
{
var thisAssembly = typeof(SwaggerConfig).Assembly;
GlobalConfiguration.Configuration
.EnableSwagger(c =>
{
c.SingleApiVersion("v1", "WebAPI");
})
.EnableSwaggerUi(c =>
{
});
}
}
I'm new to this so I'm probably missing something

first of all, it seems you made a mistake in RoutePrefix section. If you mean by defining v1/controller to use the name of your controller dynamically in the path, you should put [] around it like this:
[RoutePrefix("v1/[Controller]")]
and about the registration. you need to remove {} from your code.your code should be like the following:
GlobalConfiguration.Configuration
.EnableSwagger(c =>c.SingleApiVersion("v1", "WebAPI"))
.EnableSwaggerUi();
I recommend to register swagger directly into the Application_Start() section.
Your final code should be like this :
public class WebApiApplication : HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configuration
.EnableSwagger(c => c.SingleApiVersion("v1", "title of your api"))
.EnableSwaggerUi();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
}
and the address to refer is: http://localhost:yourProgramPort/swagger/docs/v1
I hope it is helpful.
