I took the Microsoft exam Programming in C# back in August and today I got the result that I passed. To be honest this exam was pretty easy so it isn’t the achievement of my life but it’s my first (and yet, the only one) .NET 4.5 certification.
I didn’t prepare too much for this exam, I once read the syllabus and take a look on the async/await pattern new in .NET 4.5 and programmed in C# all day in the job. What was a little striking is how this one revolved around syntax questions. Those are very hard to answer wrong if you’ve worked with C# for a while.
Anyway if you’re pursuing this exam you might read a comprehensive C# book, such as C# in Depth or Pro C# 5.0 and the .NET 4.5 Framework and you are pretty much over prepared yourself.
