Here’s a plug for a book on .NET 3.0 Windows Workflow Foundation, written by a colleague of mine.  It’s called Pro WF, by Bruce Bukovics, and is very well written.  You can read my review on Amazon here.

Bruce discusses more about WF, and .NET in general, on his blog.  Maybe he’ll reference my blog about his blog, and we’ll have a circular reference.  I wonder if that will cause any problems with some search engines.
