The System.ComponentModel.Composition.CompositionException is thrown inside the AppManager.cs. I think that is why your system wants to have that file.
As far as I understand the function that throws the error combines the AppManger with the DefaultDataManager, the SerializationManager and the extensions that were found.
That means if any of those have an error that causes them not to be combineable you'd get that CompositionException.
Try to remove the plugins and the extensions. If your program works afterwards it's one of them.
