I finally had a small break (read time between 2 contracts) and had time to go for the 70-548 exam (PRO: Designing and Developing Windows-Based Applications by Using the Microsoft .NET Framework).
With that 3rd exam in 3 months, I am now a full MCPD - "Microsoft Certified Professional Developer" (http://www.microsoft.com/learning/mcp/mcpd/windev/default.mspx).
