    Library\PackageCache\com.unity.inputsystem@0.2.8-preview\InputSystem\Plugins\OnScreen\OnScreenButton.cs(1,19): error CS0234: The type or namespace name 'EventSystems' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)

    Now, i get a lot of these.

    How comes ?

    Switched to the 2019.2 beta 1

    Yeah.

    You can recreate with a blank 2019.2.0b1 Project, importing Input System.
    Something has changed !

    Firstly rolling back to 2019.2.0a14

    Unity 19.2 recently moved UGUI into a package, so other packages referencing it now need to do that explicitly. Will fix this in the next input system update.

    In the meantime you can change the content of Unity.InputSystem.asmdef to:

    Code (JavaScript):
    1. {
    2.     "name": "Unity.InputSystem",
    3.     "references": [      
    4.         "GUID:2bafac87e7f4b9b418d9448d219b01ab"
    5.     ],
    6.     "optionalUnityReferences": [],
    7.     "includePlatforms": [],
    8.     "excludePlatforms": [],
    9.     "allowUnsafeCode": true
    10. }

    There is documentation or how to do it explicitly, because all my code is broken because of this.

    You can select the .asmdef file in the package in the inspector(it will have a 'puzzle piece' icon), and inside the import settings, under 'Assembly Definition References,' add a new reference, and then choose 'Unity.ugui' from the list available.

    @pinkhair In Unity version 2019.2.0f1 everything is disabled in the inspector, so I can't choose any other reference. Also tried manually editing the file as suggested by unity-marcus above to no avail.

    Ah, well, I dunno about that; it definitely works in 2019.3.0a4.

    I have had the same problem. The issue was with build settings - I've changed it from x86 to x86_64
