All my xaml's in WPF are giving me the following error:

System.IO.FileLoadException
The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

I'm using Visual Studio 2010 for this. If I use VS 2012, the exceptions are gone and everything is working fine. I've also tried to go under properties -> debug -> and disable 'Enable the Visual Studio hosting process'. I don't have any special characters in my assembly name. It's just called SeatingPlans Anything I'm missing? Don't really get it why VS2012 shows my xaml, but VS2010 doesn't.

c#
wpf
exception
.net-assembly
