Unhandled Exception: System.Reflection.ReflectionTypeLoadException

Question

After loading Unity and my project this morning I saw this error, preventing me from doing any play testing in the editor. Any ideas on what is going on?

 Unhandled Exception: System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded.

Had the same issue popping up for no apparant reason in my Unity 5.4 project with Unity IAP and Analytics. I noticed that all Unity Services were disabled but, other than described by Shibli, they were not only disabled, but disappeared completely from all menus and tabs.

I fixed it the following way:

outside of Unity, remove the folder "Plugins" from your project (or the Unity Store-related stuff, if your plugins folder contains more stuff)
switch back to Unity, so that it will update the project's files.
switch back on Unity services, which should again be available by now.
add back the "Plugins" folder into your project.

Hope this helps.

Cheers, Robert
