Using silverlight client version 0.5.2 and the code below invoke is only fired one time. This same code works fine using the standard .net client. This started happening a couple of versions ago.

Thanks,
Nabil

var conn = new HubConnection("http://localhost:55911/");
_hub = conn.CreateProxy("Chat");
_hub.On<string>("AddMessage", message => Deployment.Current.Dispatcher.BeginInvoke(() => Items.Add(message)));

conn.Start().ContinueWith(t =>
{
                    _hub.Invoke("Send", "Hello there from silverlight");
                    _hub.Invoke("Send", "Hello there from silverlight");
                    _hub.Invoke("Send", "Hello there from silverlight");
 });

Try looking at the requests in fiddler and see if they even make it to the server.
You're also not observing any exceptions, if you call .Wait() on the end, what happens?
Is there a concurrent request limit on Silverlight?

Silverlight will use the browser network stack by default (mine is IE9). This was working fine in Silverlight a couple of releases ago (some time last week).

They get to the server but the server is not able to call back to the client for the second and third invokes. The first works fine.

Even tried IIS (windows 7) and no luck with that either. This has to be easily reproducible. Don't think I am doing anything wrong. I have checked a number of times.

It was only a few of lines of code to repro which I posted above. If
you need a full repro solution let me know and I should be able to
post in a couple of days as I am travelling at the moment.

I'll try to repro and make a fix for 0.5.3 when I do. VS2012 on a .NET 4.0 application or .NET 4.5?

I saw this happen to me as well in 0.5.2 so I am glad a fix is on the way. I am using VS 2012 RC and .NET 4.5. I first noticed it when one of my Firefox browsers (v 13) decided to connect via Long polling instead of serverSentEvents. Not sure why it auto connected as long polling but it did. So of course I have to ask.... Any idea when 0.5.3 will be release ? :)

No problem I understand. Like they say it never hurts to ask.

0.5.3 fixed this for me as well. It took me a while to find this thread when I searched on "signalr network error 500", so adding that tag here. :)
