I’m working with an old windows app in visual studio 2005. A webserviced referenced in the original app has 2 functions and when i peak inside the auto-generated reference.cs file I notice a couple of other functions to allow async calls have been geenrated i.e. BeginWhateverFunctionNameIsCalled and EndWhateverFunctionNameIsCalled.

My problem is that I’ve created a new windows app and added the same web references but the Begin and End functions are not generated in my reference.cs proxy class. Anyone know whats going on?

    It is VS2005, and isn’t generating the async methods. OK; is it .NET 2.0 or .NET 3.0 (via the VS2005/WCF add-on)?. It looks like “wsdl.exe” (the original) will generate “FooAsync” methods, but WCF (“scvutil.exe”) may generate the “BeginFoo” pattern. You might also look to see if you have used WSE*, for example, “wsewsdl2.exe” or “wsewsdl3.exe”.

    My bets would be of the WCF version. Note also that different frameworks (Silverlight etc) have their own proxy generation classes.
