Sourcesafe: The project you are attempting to open is a source controlled FrontPage Web...

When opening a web-project from Visual Sourcesafe 6.0d in Visual Studio .NET 2003 we sometimes get this error:

"The project you are attempting to open is a source controlled FrontPage Web and cannot be opened directly from source control. Please use the Open Project From Web command instead."

If we look at IIS, we see that the VS.NET created only a virtual directory instead of a virtual application.
Google was no help at all, but it looks like we've found a working solution:

- Delete that virtual directory in IIS
- Reload the project from Sourcesafe
- Continue until you get the 'Set Project Location' dialog box
- Go to the IIS Manager and create the virtual application(s) you need, pointing to the directory where Sourcesafe will place the files
- Go back to Visual Studio .NET and continue as you normally would
- Happy programming!
