The following code:

' Create the operation context scope needed to add headers
Using loSOAPSVC.oOperationContextScope = New System.ServiceModel.OperationContextScope(loMyService.InnerChannel)

End Using

...would cause the designer to report this:

"Operator '=' is not defined for types 'System.ServiceModel.OperationContextScope' and 'System.ServiceModel.OperationContextScope'."
