The Microsoft Certified Professional Developer: Windows Developer (MCPD: Windows Developer) certification demonstrates that you have the comprehensive skills that are required to build rich client applications that target the Windows Forms platform using the Microsoft .NET Framework 2.0.
MCPD: Windows Developer candidates must first complete the requirements for the MCTS: .NET Framework 2.0 Windows Applications certification (two exams). After they achieve this certification, candidates can earn their MCPD: Windows Developer by passing one additional exam.
If you are a Microsoft Certified Application Developer (MCAD), you can upgrade to the MCPD: Windows Developer certification by taking one upgrade exam. You do not need to obtain the MCTS prerequisite credential if you take the upgrade exam.
