If you - just like me - are in the unfortunate situation that you cannot migrate all your Visual Studio 2003 projects to Visual Studio 2005 yet, and grow increasingly jealous about those cool new VS 2005 productivity enhancements like improved IntelliSense, refactoring or code snippets, there is a remedy: JetBrains ReSharper. It comes equipped with a rich set of features, such as intelligent coding assistance, on-the-fly error highlighting and quick error correction, support for code refactoring, and a whole lot more. We have been using it under VS 2003 for a while, and it has saved us tons of time.
