Cool VS.NET addins from Wndtabs:
- Spelly - spell-check your source code from within VS.NET. Can check all code, just comments, or just a selection.
- Project Line Counter - counts the lines of code per file for the entire solution. Get the report in XML, HTML (with XSLT), or CSV. They even provide a sample worksheet that shows some statistical analysis.
Both work all the way back to VC++ 5 (supports VB.NET too). Cool!
