Reflection.ReflectionTypeLoadException for MahApps DLL

Question

Today I've had a curious issue. After making a realse (I did not change any references), i get an Reflection.ReflectionTypeLoadException which says, that it coul don't load a type in MahApps.Metro .

The curious thing is, that I have no assembly which references MahApps .

What else could cause this issue? I've debug and searched a lot, but could not find anything.

EDIT

Sometimes the exception occurse only the first time I do some action. If i open a windows the second time, everything works.

Thank you all!

You can use a tool like ILSpy find where the dependency is coming from. Just inspect each assembly in your bin folder until you find the one that references MahApps.
