@kirsan31 , linked PR is being tested. I am hoping to merge that this week and I will check if this scenario is one of those cases and update it here.

np. I am also looking at VS specific solution that we can service. I will link that as well when it is ready.

Targeting 8.0 and up is working. But VS solution has a few SystemAware instances to read the Project File's awareness.
