Windows Developer .Net 3.5

I have upgraded MCPD Windows Developer .Net 2.0 to .Net 3.5 by passing following exam 70-566: Upgrade: Transition your MCPD Windows Developer Skills to MCPD Windows Developer 3.5

The exam has two parts, the Technology Specialist part, with 20 questions and the second one, the Pro, with 25 questions. From 'upgrade' exam I expected more questions strictly about .NET 3.5 features but actually there were plenty of general Windows Development questions, many similar to those from both TS and Pro .Net 2.0 exams. The main benefit is that in order to get .Net 3.5 certification you have to, instead of passing two exams with about 45 questions each, pass one two parts exam with 45 questions.

I have been thinking about next step and decided not to extend skills with other technologies (e.g. ASP.NET), but rather specialize and improve skills in my current domain, which is .Net Windows Development.
