Hidden deep on the WSE page of the MSDN Web Services Developer Center are two Hands On Labs for getting up to speed with WSE around messaging and using policy to implement secure Web services. These are great ways to get your feet wet with WSE and dig pretty darn deep into the capabilities WSE provides.
But the original labs were only available in C#. We just posted new versions that were tested w/ the new SP2 release of WSE 2.0...and now the download also includes Visual Basic versions of the labs!
Thanks to Mark for getting these ready for prime time, and for Aaron for creating them in the first place.
