Using 2 diffrent .Net versions depending on Config

Hi.

I want to use 2 diffrent .Net versions on the same project.

This is because i want to be able to compile my project to PC and to Windows Mobile.

I have seperate the code that is diffrent by creating 4 new project configurations instead of the standard 2 "Release" and "Debug".

PCRelease, PCDebug, WindowsMobileRelease and WindowsMobileDebug

Then i use #if WINDOWSMOBILE do

Problem with this is that i only know how to load 1 .Net version into VS 2005 and i dont know how i could alter the version beeing used depending on my project configuration.

Any suggestion?
