UWP templates broken in Visual Studio 2019?

I tried to use the trick described elsewhere to install Monogame templates for VS2017, then copy over the templates to my VS2019 (preview), using a recent devbuild that has a working pipeline tool (3.8.0.1047)

This worked and I was able to load and compile the “MonoGame Cross Platform Desktop Project” template, but both the UWP templates (the regular and the Core one) seem to be broken with the following error messages:

It would be great if VS2019 was officially supported together with a working pipeline tool without any hacks to get it to run.

OK, my mistake, it turns out the UWP components were not installed yet in VS2019!
