What product are you using? My Enterprise Developer samples set includes various WCF samples.

Start > Micro Focus Enterprise Developer > Samples > Visual COBOL Samples

Then in the samples browser, select Windows Communication Foundation in the left-hand pane. There's a "Web WCF Service" sample, among others.

I found the samples ... Thanks

I am using .NET Cobol Webservices for about 8 years. If you like I can send you a small VS 2010 Webservice Solution (created for a support case) demonstrating usage of Cobol.RuntimeServices in a multithreading environment (IIS).
