Hi, just was able to test and debug. I did not found a solution. I posted a question to the LibUA forum - the basis library we are using.

I did like you described above. Do I need anything to start the OPC server. I even was not able to connect with OPCWatch and anonymous mode. Do I need to configure a project in DeviceXPlorer?

This feature will be included in the next release (2021.14) which will be available about 17.02.2023

There first error is about I18N - please check if folder Tools/ZIP is in our project and delete that (and every code which is using ZIP - it is not essential needed)

As far as I see the SharedMemore Interface is not able to be compiled.. I think SHM is not available on Hololens. Are all unnecessary Interfaces deleted (by deleting the interface folder) which are in the Interfaces folder?
