Can't build Google Tango demo scenes on 2017.2.0b9

Using 2017.2.0b9 with the new XR project settings to build the Tango demos on an Asus Zenfone AR. If I check the Tango enabled box in XR settings the build fails with this error:

Code (CSharp):

From what I understand it means that the Tango library is being added twice, but if I don't check the box the build finishes successfully but the app crashes on startup. Thoughts?

 

Yep... the only way I was able to get it to work was to roll back to 5.6

Then the demo/examples compile fine (I was able to mod one to create an AR demo / prototype)

 

How did you do it with 5.6? I made a build but just shows a black screen in many of the scenes like the marker recognition scene, noone scene works
