Export Visual Studio 2012 to 2010 sln format

Question

My teacher is complaining that he can't read the VS2012 format on his VS2010 environment. I looked around in settings and so on but couldn't find anything. How can I give the project in an VS2010 readable format to my teacher?

Answer 1

Modifying sln manually

1. Backup your project folder (copy/paste to another location, like a folder called "backups")
2. Open sln file on wordpad

3. Change the "header" of opened sln to below (the first lines that matches mentioned lines below, except by version number/name):

   Microsoft Visual Studio Solution File, Format Version 11.00
   # Visual Studio 2010
   

I'll see if there is a way to do it in project options...

Answer 2

If the VS2010 installation has SP1 installed, then it should be able to read the VS2012 solution file.
