C# – WCF async call return a 10054 error: “An existing connection was forcibly closed by the remote host”

I have a WCF consumed by a Windows Mobile 5.0 or above application with .NET Compact Framework 2.0 SP2 and C#.

When the application consume a asynchronous "method" it throws that message. This is also the stackTrace of inner exception:

at System.Net.Sockets.Socket.ReceiveNoCheck()
at System.Net.Sockets.Socket.Receive()
at System.Net.Connection.Read()
at System.Net.HttpWebRequest.fillBuffer()
at System.Net.HttpWebRequest.getLine()
at System.Net.HttpWebRequest.parseResponse()
at System.Net.HttpWebRequest.startReceiving()
at System.Net.Connection.startReceiving()
at WorkItem.doWork()
at System.Threading.Timer.ring()

The message from the exception is:

"Unable to read data from the transport connection."

And its stackTrace is:

at System.Net.HttpWebRequest.finishGetResponse()
at System.Net.HttpWebRequest.GetResponse()
at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse()
at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse()
at System.Web.Services.Protocols.SoapHttpClientProtocol.doInvoke()
at System.Web.Services.Protocols.SoapHttpClientProtocol.doAsyncInvoke()
at WorkItem.doWork()
at System.Threading.Timer.ring()

What's happening?

If you need more details tell me!

Update:

I have two computers and on both the same error happens. One of then is a Windows 7 Ultimate 64bit, and the other is a Windows Vista Home Premium 32 bit. Maybe it is something releated to code…

Thank you.
