How to solve it? Any tips?
In the meantime, is there somewhere a pre-build package in order to test it on HoloLens?

Thank you

Hi, unfortunately there is no pre-built package, that's a pretty good idea though.
One thing I would try is rebuilding the NetworkCommunication.dll using VS 2017.
Please let me know if I can help more or if you manage to solve this.

@tinuxnet Can you please mention the unity version, visual studio version and windows version you utilized? I do not want to repeat myself. Please refer to the issue I opened #21 Thank you.

See here for the temporary fix for this issue: https://forum.unity.com/threads/net-scripting-backend-and-visual-studio-2017-3-incompatibility.487833/

This is an incompatibility issue between .Net UWP solution built by Unity 5.6 and newer versions of Visual Studio. I think updating the Unity version of this project to a version that Unity built while newer versions of Visual Studio were available would fix this, while I do not mean that would be a must as it might involve a lot of work...
