@timdeschryver, this looks great! I committed some small fixes, and I approve with those in. I also tested the app sample.
Cool that you noticed the VS for Mac tab needed to be removed for this version as well. It did. Did Rick mention that?

Thanks for the great work!

Thanks Wade, and thanks for the small fixes!
I knew that the support for Mac is dropped, and I think I saw another PR or issue also removing the tab.
