getting Pipe is broken exception when running on Windows 7

[wdstest]

I get a System.IO.IOException "Pipe is broken." exception inside PipeServer.cs
LegacyWrapper.Transport.PipeServer::SendCallResponse(CallResult callResult)
{
_fromatter.Serialze(_pipe,callResult);
}

This happens also in Win 10, but might not be shown to the user except on debugging.

InvokeFunction(data) in ProcessMessages should only be called, when data.Status != KeepAliveStatus.Close (or data.ProcedureName is not null).
