I use VS2005 and .net 2.0. I try to make an async web method call using BeginMethodName and EndMethodName. According to all documents I read, VS2005 Web Reference should generate these two methods for me for each web methods in the web service. But I check reference.vb and these methods don't exist.

Does anyone have any idea why this happens?

By the way the web service was implemented using .net 1.1.
