I managed to run the sample on Unity 2019.4

Many people in the Issues asked how to run the samples on Unity 2019.4, and I managed to run the example. I'll share what I did to get it to run so that others can hopefully avoid the time I spent experimenting and trying it out. Maybe someone with more knowledge can also fix my workarounds.

Maybe this isn't hard for experienced people, but it took a good long day to figure it all out.

To be clear, I ran the "Build2019Demo.Unity".

Relevant prerequisites

Below is the hardware and Unity version I use.
HoloLens 1st Gen
Unity 2019.4.34f1
Windows 10
Android OnePlus 5T

What I did

1. Clone master (commit 7796da6 when I did it)
2. Follow the repo's instructions
   • Run tools\scripts\CreateUnityPackage.bat in an administrator cmd window
3. Now, I can use Unity to open the project. I still had some compiling errors on Unity
4. Change packages used
   • I followed this link, which allows ASA to work with 2019.3
   • There is probably a way to update this package in the bat file process itself, but I didn't look into it
   • I updated the following libraries to these versions
     • AR Foundation: 3.1.3
     • ARCore XR Plugin: 3.1.3
     • ARKit XR Plugin 3.1.3
5. If your AR Foundation gives you compilation problems regarding obsolete API, check if it's something in 'Assets\AzureSpatialAnchors.SDK\Scripts\SpatialAnchorManager.cs'.
   • If it is, follow the same link in step 4, "Update the ASA SDK to ARFoundation 3 objects" part.
6. Now, the only problems should be coming from Text Mesh Pro. I removed references to ignoreRectMaskCulling
7. If Unity ever complains about upgrading API, just say yes.
8. After changing platforms for UWP/ Android, I did not have any compilation issues.
9. At this point, you can follow the instructions in the repo again.
10. I ran on HoloLens and managed to connect with my Android OnePlus 5T phone

I will leave this open until someone else decides to close it.
