Confused... thought projects in VS2010 VS2012 were interchangeable...

I've got both VS2010 & VS2012 installed and a solution with multiple projects that was built in VS2012 (and hosted in TFSPreview.com). My understanding is that I could open the same solution in VS2012 and it would work fine, but could go back and forth. I've got some guys who aren't on VS2012 so I need to be able to go back and forth.
However when I pulled the solution with VS2012 RC from TFSPreview.com it made a lot of changes to the *.sln and one of the web projects. Is this expected? Is my understanding not correct (being able to open solutions in both editors)? Would the answer be to have a VS2010 & VS2012 solution file?

Most project types are supported for round tripping (going from VS 2010 -> VS 2012 -> VS 2010 without changing the project). There are exceptions, though, and certain projects need to be updated to work in VS 2012.
For details on which types of projects support this, and which require updates, see: http://blogs.msdn.com/b/zainnab/archive/2012/06/05/visual-studio-2012-compatibility-aka-project-round-tripping.aspx
Note that opening the project in VS 2012 may change the .sln or project files, but it shouldn't do anything that prevents it from being opened in VS 2010 (sp1) provided it's a supported project type.
