My team is moving from Visual SourceSafe to Subversion soon, while developing/supporting a legacy project in Visual Basic 6.0, so I have a couple of questions:
My guess would be to not bother with integration and just use Tortoise SVN in Windows Explorer.
As for file types to ignore, give it a test, checkout, build, and see if any files changed (for modern Visual Studio I tend to ignore the .suo files)
