Is Visual Studio 2013 compatible with 2010 projects?

Question

VS2012 could open up VS2010 projects and leave them in a state where they would be usable in VS2010.

Does VS2013 have the same feature?

Answer 1

Visual Studio 2013 supports "round tripping" with support for solutions as far back as VS2010. There are some exceptions where an upgraded project may be required, depending on the type of project(s) in the solution. Generally, you can open and save solutions from VS2010, VS2012 and of course, any created in VS2013.
