Cannot load addin if in UI Preview mode

[Le_Bear]

I believe this is a known problem, but I would like to know if there is new APIs methods to detect if the new UI has been activated, and maybe not even load the addin if yes, as a temporary solution.

The obvious next step would be to load the addin in the new UI, with the proper method for the new UI.

Any idea when documentation about this would be available?

When the new UI was first available no add-ins were being shown.  Autodesk has done some work to map the old UI to the new so when you add your add-in into the old UI it will automatically add it into a corresponding location into the new UI.  I'm sure there are limitations to this.  There hasn't been any new API provided yet to work with the new UI.

Thank you Brian. I will test and accept your solution as soon as I see it's working. Even better if there is no changes in the API, hence nothing to do.... 🙂

Nope, does not work!
