A really nice feature in Resharper 5 is the ability to adjust namespaces for code files in a directory.

This is especially true when you move user controls or web pages that consists of a XAML file or ASP.NET page with a code behind class that needs to match.
You can adjust the namespace for all files in a directory by simply right clicking the folder in Visual Studio and select “Refactor->Adjust Namespaces…”:
