Important LINQ Changes in .NET 3.5 SP1

Dinesh Kulkarni wrote an important post about changes in LINQ introduced by .NET 3.5 SP1 that has been released yesterday.

One of the interesting changes is in the Cast<T> operator and its behavior is better described in this post by Ed Maurer. I think that the side effects of this change should be limited, because the use of explicit type for the range variable in a query expression (i.e. from int n in numbers select… instead of from n in numbers select…) is not very common. In fact, I don’t remember examples of its usage in our Programming LINQ book. Take care of this change if you used (or will use) this syntax.
