[Mono-dev] wsHttpBinding Hangs - Mono 3.0.9

[jadfab]

Hello, 

I have a self hosted service in WCF which is hanging whenever I use
wsHttpBinding from the configuration file. The code works as expected when
bound to basicHttpBinding but fails whenever I change the binding to
basicHttpBinding. 

I ran "mono -v Program.exe" and executed a SOAP request using SOAP UI , this
is the last few lines of output:

Looking into the code, methinks the WaitHandle from HttpListenerManager is
the culprit. 

var ce = SelectChannel (ctxi);
if (ce == null)
       throw new InvalidOperationException ("HttpListenerContext does not
match any of the registered channels");
ce.ContextQueue.Enqueue (ctxi);
ce.WaitHandle.Set ();

I can try to fix this on my own however I was wondering if anyone else has
encountered this problem before and what the fix was before I go digging
into code :)

Thanks in advance
