I just learnt something new and cool from one of Scott Guthries blogs: the ?? null coalescing operator in C# 2.0. I never noticed it until now, and actually thought it was part of 3.0, until a kind reader corrected me... it's been around ever since the advent of nullable types in C#.

Basically, this operator works like the T-SQL ISNULL or COALESCE function. Read all about it in Scott's blog!
