They've been making improvements over at gotdotnet.com, not the least of which is their new SCC plugin to use the GotDotNet Workspaces source control arrangement. Not only does it work very nicely in VS.NET 2005, it also works with VS.NET 2003!
It's just like working in VSS; the only difference is that since you are working via WebServices, it's a bit slower. But everything works! Really a boon to developers who like the Gotdotnet Workspaces concept and have small groups of developers who work together on a project.
The only downside is that when you want to get a project out of your regular VSS provider, IIT BREAKS and doesn't work!
But there are several fixes, the best one I've found is Soenke Schau's Sourcecode Control Switcher.
This little tray app tells you your current provider and let's you switch at will by changing the Registry entries for you. And, you don't need to leave it running. Just put a shortcut to the desktop and bring it up when you need it.
