Switch Target Framework in VS.NET 2010

Question

Is there a way to change the target framework of all the projects of a solution in one fell swoop? Changing the target on 18 projects is a little tedious.

Answer 1

Do a search on the project files for

<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>

and replace with the desired version.

Answer 2

Scott Dorman wrote a macro to do this: http://www.codeproject.com/Articles/74805/Visual-Studio-2010-and-Target-Framework-Version.aspx
