For various reasons I have decided its time to take some .NET exams, I'm starting with 70-536, Microsoft .NET Framework 2.0 - Application Development Foundation.
As part of the study, I'm going through some practice tests and realise there is a lot of stuff that I've never or rarely used in 6-7 years of .NET experience (mostly building web sites).
Have I been missing out? Is there something in this exam that I should have been using in my day to day work?
Have you used BitVectors, created dynamic assemblies, overriden default evidence for assembly etc in your day to day work?
