I opened my project to tinker with the UI for a little bit. After 10 minutes, decided to leave it as it was so I just right-clicked in the VS.NET 2003 Proj Exp and selected Undo-Checkout on the form. My form did not restore to the prior state, so I closed and reopened the project, still, it did not restore.
I've seen this twice now. The first time I wasn't sure if it was something I did, the second time doesn't make sense. Not using anything be integration within VS.NET 2003. Using 2.0 of Vault (single-user free license).
Bug? Undo checkout did not undo!

There is an option for undo to leave the file or revert it. Vault by default leaves the file alone, so you need to set it to revert the file back to what it was before you checked it out. In the VS.Net Undo checkout dialog, go to the top left and click on advanced options - you can set it from there.
