Crash with Could not load file or assembly MetroLog in PCL

[igorkulman]

I have a Windows Phone 8 app with Metrolog and it works fine. It references a PCL (Windows Phone 8 + .NET 4.5). When I add Metrolog to the PCL and try to use it from the PCL , the app crashes with Could not load file or assembly MetroLog.

Here is a minimal solution reproducing the problem: https://dl.dropboxusercontent.com/u/73642/metrolog-crash.zip
