AppCompat with MSIX

Hi,

I'm repackaging some (very) old apps in MSIX, and I'm facing a situation where I need to enable some app compatibility shims.

I've tried doing this with the `registry.dat` registry hive, but it doesn't seem to work. I think I've heard something about using SDB in a MSIX package once, but I might be imagining things.

Right now I've resorted to using an ImportRedirectionTable and a redirection DLL, but this only works for simple cases like Windows version lie.

It would be amazing if there was a way to use an SDB inside a MSIX, but if the registry option could work, that'll do too.

Did anybody manage to make this work?

Thanks!
