Profiling Database Activity in Entity Framework

There was a really good article on performance profiling of Entity Framework in the December issue of MSDN magazine.

The article also mentions a good third party tool called Entity Framework Profiler (There is a cost to licence), also check out Huagati Query Profiler (also has a cost, but has a free trial).
