title: Add OwinStartup class in NET Core App
body: <p>I am building an ASP.NET Core WebApp (.Net Framework). [NET Core 1.1 / net462]</p>
  
  <p>There's a standard Net Core Startup class with ConfigureService and Configure methods and the application builder interface is Microsoft.AspNetCore.Builder.IApplicationBuilder.</p>
  
  <p>Now, i need to add an OwinStartup class where i basically map to the Owin.IAppBuilder interface in this way:</p>
  
  <pre><code>  app.Map("/ServiceHub", map =&gt;
              {
                  map.UseCors(CorsOptions.AllowAll);
                  var hubConfiguration = new HubConfiguration
                  {
                      EnableDetailedErrors = true
                  };
                  map.RunSignalR(hubConfiguration);
              });
  </code></pre>
  
  <p>It is not clear to me how to run the owinstartup and net core startup class.
  Or, in case i need to add an OwinMiddleware,  how i can configure it in order to map this configuration.</p>
