Having these issues with VS2012 should not stop you from using the libraries. You can still browse the sample code of the examples application and you can still use the binaries in your apps.
This problem is not related to the Examples solution - it is a common problem with using VS when referencing multiple projects and binaries from a single location.
If you are having persistent problems you can try to copy the Examples solution folder in another folder (c:\work for example) and try to run the solution from there. Please give it a try and let us know how it goes.
