Unexpected compilation errors about missing UI module thrown when building project to Standalone after project upgrade
- Open the attached project in Unity 5.4
- Fix two script compilation errors created by some obsolete APIs (the original project was working in Unity 5.3)
- Try to do a Build and Run for Windows Standalone as a target. You will be presented with lots of errors like: "The type or namespace name `UI' does not exist in the namespace `UnityEngine'. Are you missing an assembly reference?" and the player fails to build.
Workaround: Reimport all assets (though this shouldn't be necessary). This is a regression, since building in Unity 5.3 works fine.

Try deleting C:\ProgramData\Unity\index-local.xml and see if that helps, if it does - can you say if you've used 5.4 beta before 5.4 release?

I have the exact same problem with Unity 5.3.4f1(64bit). I have tried all the possible solutions I googled none of them work.

Did not upgrade during project, but had a simular problem. deleting library solved the problem.
Note: in my case I also had an issue of UnityEditor useage also causing build errors. Unknown if it is related.

If reimport won't help try to remove Library\UnityAssemblies folder (make a backup earlier). I found out that it's resolving the problem in 5.4b20 and 5.4b21.

It was only present in migrated big project. After I deleted ..\Library\UnityAssemblies\* files and let them rebuild problem disappeared.
