Missing Namespace UI error appears when a script tried to use UnityEngine.UI

Scripting

Priority: 2Necessary for shipping a final release

-

Severity: 2Core functionality majorly impacted

After running through a few packages in the Assets Store, loading and unloading packages and DLLs, I got into a state with my project when Unity doesn't recognise "using UnityEditor.UI" in all the scripts in the Google Cloud Vision project.

This does not happen when i freshly install the Google Cloud Vision asset in a fresh new project.

To reproduce the error in the console:
- download this project
- open it with Unity 2019.2.0b3 or 2019.3.0a3 on Windows 10
- notice the compilation errors:
Assets\FrostweepGames\GCSpeechRecognition\Examples\Example\Example.cs(4,19): error CS0234: The type or namespace name 'UI' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)

Reproduced with Unity 2019.2.0b3 and 2019.2.0a3
Cannot reproduce in Unity 2019.1.0f2, 2019.3.0a2, 2019.2.0a14

    Removing and re-adding UI in the package manager resolved this issue for me.

    In my case Visual Studio 2017 underlines every usage of a UnityEngine.UI class in red, what is very irritating, but Unity 2019.3.0a3 compiles it without any errors.

    So, it is reproducable. Not saying where the fault is, could be in 'Oculus Integration', but could be in later unity as well.

    The very same happens for me. Just create a new project and install latest 'Oculus Integration' from Asset Store, last working on 2019.2.0a7 (with a prev version of OI). Latest Oculus not working on 2019.1.4f1 and 2019.2.0b4. Not much option left than keeping to an old version of both, but i'm having problem with 'OculusVRCValidator --test TestSubmitFramesWhenNotVisible' so would like to update to latest and test.
