Answer 1

to convert visual studio 2010 solution file (.sln) to visual studio 2008 solution file (.sln) simply follow these steps:

1. in .sln file replace "Format Version 11.00" to "Format Version 10.00"
2. in .sln file replace "# Visual Studio 2010" to "# Visual Studio 2008"
3. in .csproj replace "ToolsVersion=''4.0''" to "ToolsVersion=''3.5''"
4. in .csproj replace "v10.0" to "v9.0"

Answer 2

I've just created a little batch file that will convert between VS2008 and VS2010 (vice versa) at will.

It rewrites the strings found at http://blogs.msdn.com/rextang/archive/2009/07/06/9819189.aspx between both versions in an automated fashion.
