parameterInfo.Name = "(ReturnValue)";
parameterInfo.ParameterType = typeof(string);
parameterInfo.Position = -1;
info.Parameters.Add(parameterInfo);
receive.ServiceOperationInfo = info;

Dim receive As New ReceiveActivity()
Dim info As New OperationInfo()
info.Name = "Echo"
Dim parameterInfo As New OperationParameterInfo()
parameterInfo.Attributes = (CType((System.Reflection.ParameterAttributes.Out Or System.Reflection.ParameterAttributes.Retval),  _
                            System.Reflection.ParameterAttributes))
