No one have similar problem?

 

Have never seen this particular error scenario. what platform are you targeting?

 

I ran into this same error when refactoring my project to break up the scripts I have to be compiled in separate DLLs. Are you using any external DLLs in your project? In my case, I had to go to the solution/projects I created for the separate DLLs, and make sure the References like to UnityEngine.dll or any other dependencies were valid and found, rebuilt the DLLs, and then copied them to my assets folder.

Another problem was my Target framework .NET framework 3.5 or .NET framework 4.0 was inconsistent across the external DLLs, so I made sure they all used the same one.

I would probably start deleting DLLs from your project until the errors stop so that you know the culprit DLL. Just make sure you delete the DLLs in the right order so that the dependency DLLs it relies on are all there before you call it the bad DLL.

 

are you on windows 10? i get same error on w10TP when targeting windows store apps

I'm on Windows 8.1. That looks like DLL issue. The dependent DLLs are old or missing.

 

yes, i googled it the dlls needs to be in plugins folder (Plugins/Metro/mydll.dll) or something like that, i sloved it with not to use dlls

 

I had the same issue, deleted uSequencer plugin and voila: Solved!
Could be a plugin or a dll issue.
