Texture2D.alphaIsTransparency API is editor-only but lives in UnityEngine.dll
-e: Using Texture2D.alphaIsTransparency in a script causes the build to fail with the following error:
error CS1061: Type `UnityEngine.Texture2D' does not contain a definition for `alphaIsTransparency' and no extension method `alphaIsTransparency' of type `UnityEngine.Texture2D' could be found (are you missing a using directive or an assembly reference?)
-repro:
* Open attached example project.
* Go to File > Build Settings
* Select PC, Mac & Linux Standalone
* Select Target Platform "Windows x86"
* Press Build
* NOTICE the build fails.
Expected:
Using Texture2D.alphaIsTransparency should not break a build.
If this is intended to be an editor-only method, consider moving it in to UnityEditor.dll.
Update: This setting is available only in the Editor scripts. Note that changing this setting will have no effect; it must be enabled in TextureImporter instead.

I'm having the same issue with version 2020.3.42f1 as well. So I can say the bug is still there in this version as well.

I tested this on Unity3D version 2018.2.2f1 and the following error appears: error CS0117: 'UnityEngine.Texture2D' does not contain a definition for 'alphaIsTransparency'.

Same problem. Hardware cursors won't work correctly using dynamically-loaded PNG textures because I can't set alphaIsTranparency in the game build, while it works fine in editor.

I can confirm the issue is still with us in 2017.3

I am using texture arrays. At first run i build two different texture arrays; one for opaque textures and one for transparent textures. This works perfectly in the editor.
However when I try to compile to build i get error 1061' same as the others.
Please fix this as I need to use it at runtime to determine if a texture is transparent or not! Otherwise I don't know which texture array to put it in.
NB I *can* do a workaround by naming all trans texures with a leading underscore and checking the name but this is (a) Slower than checking a alfa value (b) Kludgey (c) Prone to errors - i might accidentally underscore a texture that is not trans, or not underscore a texture that is.
Please fix!

This bug still exists in Unity 5.5.0p3. Dynamically-created textures has artifacts on the edges. It a problem and it must be fixed.
