Regression
Yes
UnityEngine.UI reference is missing in Assembly Definition Assemblies and Plugins
To reproduce:
1. Download attached “UnityUIReference.zip" project and open in Unity
2. Open Console window
Expected results: There is no Error
Actual results: There is Error:
"Assets/AsmDef/Test.cs(1,19): error CS0234: The type or namespace name 'UI' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)"
Notes:
- This issue appears both on Windows and macOS
- Notice how UnityEngine.UI resolves properly with a normal Script (Assets/Test.cs)
- Notice how UnityEngine.UI fails to resolve in the Script placed under an Assembly Definition (Assets/AsmDef/Test.cs)
Reproduced on Unity 2019.2.0a5, 2019.2.0b2 and 2019.3.0a3
Not reproduced on Unity 2019.2.0a4
Regression on Unity 2019.2.0a5

I am still encountering the issue in version 2019.3.0a5.
Looking at the files:
In my .csproj file the old UI dll (from 2019.2.0a11) entry would look like this:
<Reference Include="UnityEngine.UI">
<HintPath>C:/Program Files/Unity/Hub/Editor/2019.2.0a11/Editor/Data/UnityExtensions/Unity/GUISystem/UnityEngine.UI.dll</HintPath>
</Reference>
If we go look into the same path in the 2019.3.0a5 path, the GUISystem folder under .../Editor/Data/UnityExtensions/Unity/ is missing.
If I copy it manually from the old version (2019.2.0a11) into the new (2019.3.0a5) and restart Unity I get these kind of errors:
Library\PackageCache\com.unity.textmeshpro@2.0.1\Scripts\Runtime\TMP_Dropdown.cs(170,16): error CS0433: The type 'Image' exists in both 'Unity.ugui, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' and 'UnityEngine.UI, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'
Got a similar errors with the analytics. So I uninstalled the the 'com.unity.analytics' and 'com.unity.textmeshpro' and now the project builds. But the UI is not showing. Nothing on the UI canvas.
Had to revert back to 2019.2.0a11.
