I created a new Windows Phone Game (4.0) project in Visual Studio Express 2012 and added the Farseer project to the solution explorer. But adding a reference to the Farseer project is not working. I always get this error message:
A reference to 'Farseer Physics XNA WP7' could not be added. References with different refresh levels are not supported.
What is wrong? How can I use Farseer in Windows Phone 7/8?
I uploaded the two projects on pastebin.
