如何在ASP MVC中使用Global.asax而非Startup.cs配置SignalR？

Question

SignalR Requires Owin Startup Class, but my application works with Global.asax class.

public class Startup
{
   public void Configuration(IAppBuilder app)
   {
      app.MapSignalR();
   }
}

if I add the startup class, my asp MVC project will have two start classes (global and startup), is it OK? or I should only apply one of them and move my global class to startup class?

You can mark which class in an assembly will be automatically used by Owin in the startup.

In my example, I declared it in the Startup and pointed to it using OwinStartup eg

using Microsoft.AspNet.SignalR;
using Microsoft.Owin;
using System.Net;
[assembly: OwinStartup(typeof(YourProject.Startup))]


namespace YourProject
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            var hubConfiguration = new HubConfiguration
            {
                EnableDetailedErrors = true
            };
            app.MapSignalR(hubConfiguration);
        }
    }
}

If you are using Owin , you must use the Startup class instead of the Global.asax .
