Unity.InputSystem does not appear in the assembly definition assets selector.
I’m using Unity 6000.0.0f1 and Input system 1.8.2. Active input handler is setted to “both”.
Given a custom assembly,
when importing “UnityEngine.InputSystem” in a script which belongs to the custom assembly namespace,
then the following error appear in the console:
error CS0234: The type or namespace name 'InputSystem' does not exist in the namespace 'UnityEngine' (are you missing an assembly reference?)
but input system can’t be selected in the assembly definition reference asset selector.
