From Visual Studio select File | Source Control | Change Source Control. This dialog allows you to unbind your solution and projects from source control.

Thanks for that, but..

I meant without involving VS.NET.  That is, editing the .sln and/or .csproj files and/or others.

As an example, I've taken a solution I want to use as a sandbox project -- based on an existing VSS project -- saved it to a non-Working Directory and deleted all the *.*scc files.  I then edited the .sln removing the GlobalSection that referred to source control, and I scanned each of the .csproj files involved, looking for any reference to source control -- didn't find any.

When I open the .sln, I still get "This solution appears to be under source control, yet..."

Make it stop!  

Thanks again - Jonathan

Editting the .sln and .csproj is discouraged and not supported. Just copy the solution to the non-working directory and open it in VS. Then use Change Source Control to remove the source control association. After this it won't complain about source control.
