* Add check for dependency resolution

* Fix typo in filename

* Remove cache from resolve check

* Combine commands into one run

* List project files in downgrade action
This should reduce the number of individual CI jobs

* Add General registry

* Remove CompatHelper CI

* Apply suggestions from code review
