Hello, Michel.
>What I mean is that you have to make sure that your code in .NET uses Soap Client 3.
This is the same issue I've faced some months ago: .NET doesn't *not* use the same Soap Client as VFP; instead, it access Web Services natively by means of classes contained in the Framework. I haven't had the chance to solve the problem by that time.
