I think you have two options here:
1. If you have Visual SourceSafe, check the code in before starting your
experimentation and then check it out again to try the different options.
2. Assuming the projects within the solution are all sub-folders of the
solution folder (on the hard disk rather than in the solution explorer) then
you can just make a copy of the solution folder and all its sub-folders
somewhere else on your hard disk and work on it independently from there.
A solution is just a collection of projects. A project is a set of files
that build to create an assembly. So if you have two assemblies in your app
you would normally have two projects in your solution. When you start a new
project from the start page you are actually starting a new solution that
contains one project.
I hope this helps.
