How are the packages published?

[poklau]

I tried to publish MyMainApp, ActivatableOptionalPackage1 and ActivatableOptionalPackage2 in Visual Studio which create 3 sets of msixbundle & appinstaller files for me.

Then I updated MyMainApp.appinstaller to include ActivatableOptionalPackage1 and ActivatableOptionalPackage2 as OptionalPackages as per documented in https://docs.microsoft.com/en-us/windows/msix/app-installer/how-to-create-appinstaller-file . Installing MyAmainApp.appinstaller after editing the appinstaller file only seems to install MyMainApp but not the other 2 packages.

How are these working together in the actual publish/deployment cycle?

Are optional packages with downloadable content (DLC) still supported? I do not see any support in the Partner Center.
