Difference between Unity DLL and UWP DLL?

[techtide]

Problems developing for the HoloLens were apparently sorted out in milestone 0.16. Issue #6, "Error compiling for HoloLens", says that the Browseable attribute which supposedly resulted in problems for HoloLens deployment has been removed in the Unity DLL.

I am not clear on one thing: How are the Unity and UWP DLLs different? In issue #6, micjahn wrote, "Next version of ZXing.Net will included binaries for unity without the attribute", and also referenced the use of a newly made UWP DLL in Unity. Now there are both Unity and UWP DLLs, so what's the difference? Considering the said Unity DLL has now been stripped away of the Browseable attribute as said in that issue, does that mean the Unity DLL should now support HoloLens development? In either case, can the UWP DLL be used in Unity?

The Unity version is built against the UnityEngine assembly and contains special BarcodeReader and BarcodeWriter classes which support the Color32 struct. UWP version is lacking the assembly reference and Color32 support. I don't have a Hololens environment, so I can't say anything to the last questions.

Okay. Thank you micjahm, I will try using the Unity DLL and uploading it to the HoloLens to see if it works. I think that that in the end, Unity translates everything to UWP, but I am not 100% sure - I will update this thread accordingly.
