Here. A VS.NET add-in that provides the following C# refactoring operations:
-Encapsulate Field
-Extract Method
-Inline Temp
-Introduce Explaining Variable
-Move Method new
-Rename Field
-Rename Method
-Rename Property
-Rename Local Variable
-Rename Parameter
-Replace Magic Number with Symbolic Constant
-Replace Temp with Query
It seems to be implemented in Java and then ported to .NET via J# and the web site has the coolest little visitor counter control.
