Add the following tools to your toolset if you're doing doing Continuous Integration with your .NET projects:
AnkhSVN - A Subversion SourceControl Provider for Visual Studio. The software allows you to perform the most common version control operations directly from inside the Microsoft Visual Studio IDE. With AnkhSVN you no longer need to leave your IDE to perform tasks like viewing the status of your source code, updating your Subversion working copy and committing changes. You can even browse your repository and you can plug-in your favorite diff tool.
VS Command Shell - VSCmdShell provides users with a shell window inside the Visual Studio IDE that can be used for Visual Studio commands as well. Current version allows user to use either Windows Command Shell (cmd.exe) or Windows PowerShell.
