CodeRush Xpress for C# and VB - FREE
CodeRush (and Refactor! Pro) from DevExpress are my Visual Studio add-ins of choice. They’re based on the “DXCore” engine, which makes writing your own Visual Studio add-ins a breeze.
DevExpress has released a free version of their CodeRush tool called “CodeRush Xpress” for users of Visual Studio 2008. It includes 60+ refactorings as well as a host of additional helpful functionality. If you have not treated yourself to trying these amazing tools, this is a great way to give it a run - huge value, no cost to you.
