MahApps.Metro: Missing method exception using 1.1.3-Alpha

Hi,

I’ve set up a sample project to try the new DialogCoordinator functionality of the next version of mahapps.metro. It works very well on my virtual machine that has windows 8.1 and VS 2013 community.

On my work machine, it compiles fine, but throws a runtime error during the initialization of the main window. I will include the stacktrace below, although I apologize my work machine is localized in french and is locked down administratively. Hopefully it will still help. The OS is windows 7 Ultimate 64-bit and I have VS 2012 pro.

From the inner exception, it’s like it cannot find a method from mscorlib. I have verified while running, and the assembly is loaded correctly from the GAC at runtime…

The interesting thing is that everything works fine with the latest stable build from Nuget (1.1.2) if I comment out the new functionality from my code.

Thank you for any insight!
