In addition to my responsibilities at RSK I also teach for developmentor, and this summer we are trying something new. We are running days of events, so you don’t have to give up a whole week from the office to attend a training course during August we are running a day of .NET threading featuring C# 5 and Visual Studio 11. So at the end of the day you will be up to speed on threading for .NET 4 and have a good insight to how things will be different in C#5 when it ships.
In addition to the days of threading we are running a day of design patterns, so if you still find yourself using the same techniques to solve problems, feel your OO skills are getting rusty then come along for a day, and immerse yourself in OO and design patterns.
