the answers i got from unity are :

• http://answers.unity3d.com/questions/636739/reflectiontypeloadexception.html
• http://answers.unity3d.com/questions/614268/added-custom-dll-internal-compiler-error.html

and none of them helped me.

Answer 1

The problem is caused by the Unity.PackageManager.dll in your project. Delete that and it will be gone.

You've also got a folder under Editor that contains a bunch of editor scripts for Standard Assets, but you don't have Standard Assets Installed, so you're going to get a bunch of compiler errors from that. Delete the Editor folder or install Standard Assets and it will work.

I'm not sure where you got the tutorial files, but nothing in this project seems to work correctly. All the scenes are empty. I would advise you go find a different tutorial.
