@Arlodotexe can we try this property from PowerToys (thanks @crutkas)? microsoft/PowerToys@main...dev/crutkas/testWinApp1.6p1#diff-47ade91915b4663302faffd533920a7af2359db7b717154c93a886448c0430c4R20-R29

Now that we're updated to Preview1, it looks like we're encountering this error:

• "XamlCompiler error WMC1006: Cannot resolve Assembly or Windows Metadata file '[...].dll'
• Subfolders are all present in the bin folder after build, but no files. They were output then removed during the build.

Sounds like the issue stems from the way 1.6-preview1 has its targets ordered. The workaround is to avoid running the Clean and Build tasks at the same time on the app head. I suspect this will be fixed before the wasdk 1.6 stable release.
