Debugging LINQ queries using Visual Studio 2010

I am looking for a reliable and an easy way to debug LINQ queries. I understand I can do the following:

1. LinqPad (Needs license)
2. Using the technique described here (Need to update linq queries with selects)
3. Extended Immediate window (Not updated for VS 2010 environment)

Has 开发者_如何学编程anyone come across anything that can be integrated with VS 2010?

Any help? Thanks
