Preparing for the Web Services DevCon today.
I just wrote a little C# project wizard for VS.NET that's the giveaway with my talk: "ASP.NET Soap Extension" creates a SOAP extension complete with format extension (WSDL annotation), WSDL importer (client), WSDL reflector (server), project installer (for use with MSI) and a "headers.xsd" to contain the header schema. The resulting projects don't do much (of course) but it a few hundred code lines of work already done and the tricky things like machine.config installation already covered.
