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

Impressionante como este tipo de problema é recorrente na Unity! As vezes dá vontade até mesmo de desistir! O problema continua nas versões mais novas! Qual é o problema de vocês?

...the issue re-appears always when I create a new C#-script inside one of my project folders. Could be fixed the same way (downgrade to VSCode package 1.1.3, close Unity, open it again and upgrade to 1.1.4)

upgraded to 2019.3.0f6 and had the same issue with VSCode. Fixed it by downgrading the VSCode package to 1.1.3 and then back to 1.1.4.

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.
