How To Open Solution VS2012 Using VS2010

Hi, I was just got a problem while opening solution from my friend that he use VS 2012 while I am a VS 2010 user. Every time I tried to open the solution, VS always reject it. I got a simple solution. There is only 3 step ahead and you can use your 2010 to open 2012 project. Here is the steps:

  1. Open solution file (.sln) in a text editor and change Microsoft Visual Studio Solution File, Format Version 12.00 to Microsoft Visual Studio Solution File, Format Version 11.00
  2. Open application configuration file (App.config) in a text editor and change sku=".NETFramework,Version=v4.5" to sku=".NETFramework,Version=v4.0"
  3. Open project file (for C# language .csproj) in a text editor and change <TargetFrameworkVersion>v4.5</TargetFrameworkVersion> to <TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
Done! You now can open the project using vs 2010
