*coughs* MCAD is an old certification - if you look at the versions, it's talking about .Net 1.0 and 1.1, which are retired.
Microsoft Learning's certification pages do list the modern 3.5 and 2.0 certifications which are currently valid, and I know that they're starting the process of writing the exams for .Net 4.0. MCTS is the 'entry' level cert (equivalent to the SCJP), and MCPD is the advanced.
I'm certified, both .Net 2.0 and 3.5 in C#, if you have questions. You can also search this forum - we've discussed Microsoft's developer certs previously.
