  • npx react-native init demo --template [email protected]
  • cd .\demo\
  • yarn add react-native-xaml
  • npx react-native-windows-init --version 0.64.0-preview.12 --overwrite
  • yarn windows --logging

Result:
the last step of the build fails with a lot of errors like:

Looks like a case of microsoft/cppwinrt#452 - tracked by microsoft/xlang#719 and internally by https://task.ms/23751686

Fix will come from elsewhere, so we won't continue to track on this repo. Hopefully this issue will help people with searches looking for support on this.

Key thing, this is the workaround:

Subsequent builds succeed, but the first time it fails

Workaround: If you hit this, build again.
