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.

I fixed it by logging into services and then turning on the Ads. You should try and turn on one of your services too, you've probably got Ads/Analytics/In-App purchases (the ones that Unity services provides) in your game and they're turned off.

Yes, that did it! Thank you very much. I turned off and then on all my services (Ads, Analytics, IAPs) and then it worked.

It is happened to me at the moment, but I can't open "Services" tab. There is only 5 things at "Window" tab: Profiler, Asset Store, Animator, Animator Parameter and Editor Tests Runner. So, I am not be able to login Unity Services or doing something else with Unity.

If nothing helps:

1) Rename Assets\Plugins\UnityPurchasing\Bin\Stores.dll to Stores.dll.off

2) Close and open Unity3D app again

3) Now Ctrl+0 or Window/Services should work fine

4) Rename Stores.dll.off back to Stores.dll

with the step 1 you can try to login to Unity web services site if needs, I think this problem is local.

It helped me. At first time I have a class Product in global scope and it conflicted with UnityEngine.Purchasing.Product, so be aware about such things. During my work on hiding the Product class my Internet connection get broken for 5 minutes, after it was impossible to make open services by Ctrl+0 or Window/Services. Well, if it requires to be in Internet for proper work - it would not be too comfortable to write a code offline. I am on Unity 5.4.1p1

Solved my issue as well - my service window would get stuck on "loading" on project open and I couldn't resolve the errors.
