2 services (WCF Web API and ASP.NET Web API) on one host

Preconditions:
1) local DB with users

2) console application (OWIN selfhost) + Controller (inherit from ApiController) for POST requests - import users to the DB:

public class Startup

      public void Configuration(IAppBuilder appBuilder)

            var config = new HttpConfiguration();

            config.MapHttpAttributeRoutes();

            appBuilder.UseWebApi(config);

public class Start

      static void Main()

            var baseUrl = ConfigurationManager.AppSettings["BaseUrl"];

            using (WebApp.Start<Startup>(baseUrl))

            { Console.ReadLine(); }

Problem: how can I add a WCF service to the app (wcf service should return user from the DB by ID). Can anybody suggest right solution to get 2 services on one selfhost?
