Mark, thanks for your answer.
I've logged in the ESRI Early Adopter portal but I cannot find anything related to the AR/VR in the ArcGIS Runtime. Looking at available opportunities I only see one about Survey 123. Even looking for "runtime" I find nothing. Am I missing anyting?
We plan to include this functionality in a public ArcGIS Runtime release in 2019. Ideally a release earlier in the year. Please let us know if you have a project that requires delivery of a native app for use in production that uses AR and/or VR functionality in ArcGIS Runtime. We would be interested in timeline and scope of use.
