Hello, I'm trying to add SR to my existing application.
My first problem was that the SR Startup class conflicts with my Owin Startup Class. The only way I could get it to work was to disable the Owin Startup Class.
My next issue is that I go to the index.html and it doesn't prompt me for a name. It just shows the chat page.
Imports System.Web
Imports Microsoft.AspNet.SignalR
Namespace SignalRChat
Public Class ChatHub
Inherits Hub
Public Sub Send(name As String, message As String)
' Call the broadcastMessage method to update clients.
Clients.All.broadcastMessage(name, message)
End Sub
End Class
End Namespace
Imports Microsoft.Owin
Imports Owin
Imports sfa
<Assembly: OwinStartup(GetType(SignalRChat.Startup))>
Namespace SignalRChat
Public Class Startup
Public Sub Configuration(app As IAppBuilder)
' Any connection or hub wire up and configuration should go here
app.MapSignalR()
End Sub
End Class
End Namespace
