Though often accused of being buggy or downright dangerous, Visual SourceSafe, or VSS, is still the most popular source control for Windows developers. This is why news that the recently released Visual Studio 2008 is not compatible with it comes as a shock.
Richard Berg warns,
If you plan to use VS 2008 with SourceSafe, make sure to pick up the Update CTP too. Without it, some features like "Open from Source Control" will not work at all.
He goes on to discuss a CTP for the patch that corrects the issue.
