Change Target Framework on a Class Library (Visual Studios 2008)

Ok so this is a quick one but annoys the hell of of me.

Basically I am working with a 2.0 class library project and I wanted to use Linq. Now you would think when you “upgrade” the project to 3.5 using the wizard, the target framework would follow. Well, you are stupid. Now for web projects it seems you can look at the properties -> build and boom you can see it bright as day. Try doing this with a class library you and got nothin’.

Here’s the solution:

Goto the project properties -> compile -> Advanced Compile Options AND YOU WILL BE VICTORY!!11

So easy even a child could do it… after an hour of searching on google…
