Under the hood and working with .Net, TDD, Software Design, and Agile Stuff
In the absence of any other compelling knowledge, take the message of an exception at face value. Don't make up elaborate reasons in your own mind. If it says the .Net 2.0 SDK isn't installed, just go install it. Doh.
Also remember Occam's Razor too.
About Jeremy D. Miller
