Question by mbuhlmann · Aug 22, 2017 at 12:08 PM · dll namespace version conditional managed

Compiled managed dll that references Unity APIs from different Unity versions

Let's say there's some API A in Unity 5.6.x that is deprecated in 2017 and there is some other API B in 2017 that does not exist yet in 5.6.x.

Is there any way to create a compiled managed dll that uses API A when run in 5.6.x and API B when run in 2017? It doesn't seem to be possible to use conditional compilation since the defines are evaluated when the dll is generated.

As a more tangible example, 5.6.x has UnityEngine.VR.VRSettings while 2017.2b has UnityEngine.XR.XRSettings.

Can a compiled dll be created that supports both versions if the code depends on these settings?
