Last week, TechTarget published an article I wrote providing a brief introduction to WCF. 

If you haven't had a chance to look at WCF, it may be worth a look.  It's about 2 printed pages (not that you or I would print it out, because we are both so environmentally conscientious these days).  And at that length, it provides a good basic backgrounder on WCF: what it is, where it came from, what it is designed to do, and some look to the future of WCF in .NET 3.5.  It's not highly technical.

Worth reading if you are a Microsoft developer who has not yet "taken the red pill"   I hope it provides some good insight even if you're not a Microsoft developer.
