Xamarin - SignalR Hanging on connect












0















I'm trying to connect my Xamarin app to my SignalR backend which is hosted on Azure. The issue I'm having is every time I call StartAsync() on my HubConnection it just hangs the client and the request is never completed.



I have tried break pointing through the app to make sure this is actually where the hang is happening. I have tried using the exact same code on an ASP.Net Core project to confirm the SignalR connection is working, which it is, I can connect and send commands successfully. I have tried on IOS and Android both simulators and real devices and the same issue each time. Every time I hit the StartAsync the app just hangs. Each project has the latest Xamarin and Microsoft.AspNetCore.SignalR.Client Nuget installed.



HubConnection connection = new HubConnectionBuilder()
.WithUrl("URLFORCHAT")
.Build();

await connection.StartAsync();


The expected result is for the client to just connect and continue through the program just like the ASP.Net Core project does. I have seen other tutorials that have the same code as me and it is in fact working.

    Are you making any blocking calls .Result or .Wait() that could be causing a deadlock?

  • @Nkosi Thanks for the reply, No I'm not, however after more testing I have found moving the whole section out of the constructor makes the code work. Which is a good start but strange it doesn't work. I can work around this for now.
