Xamarin native iOS SignalR private chat not working

Hi,

 

I have created SignalR Hub service using ASP.Net 4.5 and published to Azure app service.

I have added SignalR client to Xamarin native iOS project and created hub connection.

 

SignalR proxy doesn't invoke method when message sent and recieve.

 

Give me suggestions, how to implement SignalR private chat in xamarin native iOS.

 

Thanks.
