The Microsoft Certified Professional Developer: Enterprise Applications Developer on Visual Studio 2005
Not that anyone should care, apart from my manager, i posted that the only remaining exam was 070-549 PRO: Designing and Developing Enterprise Applications by Using the Microsoft .NET Framework a while ago. And this morning i passed that exam 
This means that i have earned the “MCPD: Enterprise Applications Developer” certificate that demonstrates that i have the comprehensive skills required to build n-tier solutions that target both Web and client user experiences.
At this moment i am quite involved in a couple of projects using WCF and WF thus it is quite possible that i decide to take the upgrade path to MCPD: Enterprise Applications Developer 3.5 later on this year.
