Hi,
I tested the sample you provided on Visual Studio 2012 and it seems to be working fine. No error or warning messages were shown after opening the sample, and even after a clean build. Therefore, I believe that the root of your problem relies on your local configuration. I noticed that you seem to be using Visual Studio 2013, which is still in Preview, so it should be probably related to the errors and warnings you are receiving.
