As you're likely aware, we've had a new RC1 release of Vista, and along with it a RC1 release of .NET Framework 3.0.
I've gone ahead an updated the code for several chapters from the book WCF: Hands On to be compatibile with RC1 changes
You can find the code for Chapter 6 on Legacy Integration. In addition to ComPlus and MSMQ which were in the book, I've also added another sample that shows how to call WCF from COM. This allows you to empower legacy applications written in Visual Basic, vbscript, Lotus Notes to now consume WCF services.
You can find the updated samples here:
