Describe the bug

Unity gives me error while VS doesn't, i've tryed to follow the steps from https://docs.microsoft.com/en-us/windows/mixed-reality/mixed-reality-capture-for-developers

To reproduce

1. In VS try to reference the "HolographicDisplay" class
2. Add the "using Windows.Graphics.Holographic" namespace
3. See error in Unity editor while in VS is all ok

Expected behavior

Unity Editor reference correctly the namespace so i can try the MRC feature

Ah yes, since you're referencing an API in a Windows. namespace, this isn't callable by default in the Unity editor.

There's some info here about a plug-in you can import which adapts these APIs for use in-editor: https://docs.microsoft.com/en-us/windows/mixed-reality/using-the-windows-namespace-with-unity-apps-for-hololens#mixed-reality-apis

We also have built-in support for that plug-in in MRTK, but our NuGet importer (MSBuild for Unity) wasn't working well with Unity 2019 so we temporarily disabled it for the MRTK 2.3 release. If you import the plug-in manually using the steps linked above, you can use this setting if you add the correct #define.

Also, in response to

these types of questions we typically look on StackOverflow for. That way, both questions and answers are more easily findable than in the issues list of a GitHub project.

Hi thank you, this solved my issue, yesterday i was working with the !UnityEngine_Editor properties, so building a new project each time, but now i can play and test my scripts also in play mode. Thank you :)
