SignalR은 서버와 클라이언트의 실시간 통신을 실현합니다.

먼저 관련 DLL 참조
2 Startup 파일은 SignalR의 포털입니다.

using Microsoft.Owin;using Owin;

[assembly: OwinStartup(typeof(SignalR.Core.Startup))]namespace SignalR.Core
{    public class Startup
    {        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
        }
