That's ok, it happens You should just have provided me with some errors and I could have told you instantly what was wrong. It was just by pure 'experience' that I knew that not adding the System.Design reference causes loads of errors.


In case someone doesn't know how to add a reference:
Right click the project name in the Solution Explorer. Choose Add Reference. Wait. Wait some more. When the window finally pops up, scroll down and select System.Design from the list. Then click OK. A rebuild might be required.
