I just passed my first in the Microsoft .NET Framework 2.0 series of exams, MCTS 70-528 "Microsoft .NET Framework 2.0 Web-Based Client Develoment". This is one of the two tests required for MCTS .NET Framework 2.0 Web Applications certification. The other test required for this cert is MCTS 70-536 "Microsoft .NET Framework 2.0 Application Development Foundation", which I'm planning to take sometime soon.
