Change Target Framework of all the projects automatically
Recently I had a need to change all my project’s target framework to 4.0. Usually you can just right click on the project and change this by going in to properties. I needed to do this for 34 project within a single solution file. After googling I landed on an article by Scott dorman who has written nice macro to do this job automatically.
