There’s a well structured path for ASP.net developers

Which leads you on to the MCSD track
And you get to put little logos on your CV :p
Oh, and you’re not mad, the exams are quite easy and are really jsut to make you aware of what the software is capable of. I’ve worked my way through to MCITP (which is now in the process of being retired) and i need to complete another two exams for my MSCE (yes, its back!) Private Cloud. I’ve never paid for anything other than the exams in that time.
It’s pretty much a constant upgrade path for you once you get on the wagon.
