Hello everybody.


This is a short tutorial on how to change your .NET version within Unity to 4.0.x.


It’s pretty simple, just launch Unity.


Mine’s already in 4.0 equivalent. Yours might, might not be.


So, any project will be fine, you can just start a new one. We’ll actually just go new one.


Easy as, you don’t need to do this. Little test project.


  1. Once Unity’s open navigate to edit.
  2. Move down to project settings.
  3. Navigate to player.
  4. Once you’ve got to player, it may pop up in another window. You want to click other settings.
  5. Scroll down and look for configuration. Then change it from 3.5 to 4.
  6. It’ll ask you to restart. That’s completely normal. Go ahead and restart it.
  7. It’ll reload everything in the new .NET version and everything in the SDK will work perfectly fine in the next video.

Pretty simple, easy as.
