MSDN Magazine article on building custom activities for workflows

My article on building custom activities for Windows Workflow Foundation has finally posted to MSDN.  For those of you fortunate enough to get a printed copy, you got an entire week advanced screening. :) 

I tried to cover the basics of building an activity and the various components; designer, validator, etc, as well as touch on some of the things you can do for more advanced activities that need to listen for external data/events. 

 

I'll be writing more articles for MSDN Magazine on Windows Workflow Foundation in the coming months. If you have specific topcis that are of interest, post your feedback here and I'll consider it as I plan the next articles.
