ASP.NET MVC OWIN and SignalR - two Startup.cs files

Question

I have a problem with my project.

I use ASP.NET MVC with ASP.NET Identity 2.0 for authentication and I added SignalR to the project so now I have two Startup.cs file

Answer 1

Could you put both sets of code into one single OwinStartup file?

namespace MCWeb_3SR
{
    public class OwinStartup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);

            var heartBeat = GlobalHost.DependencyResolver.Resolve<ITransportHeartbeat>();
            var monitor = new PresenceMonitor(heartBeat);
            monitor.StartMonitoring();

            // Any connection or hub wire up and configuration should go here
            app.MapSignalR();
        }
    }
}

Answer 2

Move your signalr startup file to the App_Start folder and rename it to Startup.SignalR.cs. It should have this content, note that the Configure method has been renamed to ConfigureSignalR:

namespace MCWeb_3SR
{
  public partial class Startup
  {
    public void ConfigureSignalR(IAppBuilder app) {
      var heartBeat = GlobalHost.DependencyResolver.Resolve<ITransportHeartbeat>(); 

      var monitor = new PresenceMonitor(heartBeat); 
      monitor.StartMonitoring(); 


      // Any connection or hub wire up and configuration should go here 
      app.MapSignalR();
    }
  }
}

Now in the Startup.cs file at the root of your project, add a ConfigureSignalR(app) call right after ConfigureAuth(app):

[assembly: OwinStartup(typeof(MCWeb_3SR.Startup))]
namespace MCWeb_3SR
{
  public partial class Startup
  {
    public void Configuration(IAppBuilder app) {
      ConfigureAuth(app);
      ConfigureSignalR(app);
    }
  }
}

As long as all of the Startup partial classes have the same namespace, this should work.
