Been poking about with FxCop now and came across the CLSComliant attribute. Onle hazarding a guess at what this does I started including it becuase of FxCop not understanding why I was doing it

So heres the article that explains why

I now know this will help me write better CLS compliant code as it informs the complier to check the code .

Heres another example here
