C# in Depth by Jon Skeet is amazing and is great to brush up your C# skills! A word of warning though: it's excellent for developers with experience in .NET, but does not serve as an introduction to the language/framework. The knowledge is not easily applicable to other languages either. That aside - it is still the best programming book I've read thus far.
