Error: SignalRRouteExtension.Mapconnection is obsolete. use MapSignalR in Owin Startup class

I am developing a ASP.NET MVC application with ASP.NET SignalR. But i am getting error and couldn't find how to solve this. This is my global.asax class and I am getting error at here when i started the project:

public class MvcApplication : System.Web.HttpApplication { protected void Application_Start(object sender, EventArgs e) { AreaRegistration.RegisterAllAreas(); WebApiConfig.Register(GlobalConfiguration.Configuration); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); //This is what I added and this is where i am getting the error. RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo"); } }

And my connection class like at the bottom

public class NfcConnection : PersistentConnection { protected override Task OnConnected(IRequest request, string connectionId) { string msg = string.Format( "A new user {0} has just joined. (ID: {1})", request.QueryString["name"], connectionId); return Connection.Broadcast(msg); } protected override Task OnReceived(IRequest request, string connectionId, string data) { string msg = string.Format( "{0}: {1}", request.QueryString["name"], data); return Connection.Broadcast(msg); } }

This is the part that will broadcast the data which coming from the client. And also my startup class for owin is like that;

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

When i start the project this line

RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo");

giving me this error;

Error'System.Web.Routing.SignalRRouteExtensions.MapConnection<T>(System.Web.Routing.RouteCollection, string, string)' is obsolete: 'Use IAppBuilder.MapSignalR<TConnection> in an Owin Startup class.

How can i solve this?

Remove:

RouteTable.Routes.MapConnection<NfcConnection>("echo", "/echo");

and change:

app.MapSignalR();

to:

app.MapSignalR<NfcConnection>("/echo");
