Setting the Visual Studio Version for Specific Solution Files

If you have multiple versions of Visual Studio installed such as 2010 and 2012, you can easily control what version of Visual Studio will be used to open your solution when it is double clicked.

First open your *.SLN file in notepad and adjust the very top two lines in the file to the following:

• Visual Studio 2010
• Microsoft Visual Studio Solution File, Format Version 11.00
• # Visual Studio 2010
• Visual Studio 2012
• Microsoft Visual Studio Solution File, Format Version 12.00
• # Visual Studio 2012
