How to force a Solution file (SLN) to be opened in Visual Studio 2013?

Question

I've read "Visual Studio 2012 doesn't convert vs2010 solution?" and followed the suggestion to "Save As..." the solution file.

Still it opens in VS 2012 by default.

My question:

How to change a SLN file to force it being opened in Visual Studio 2013?
