Answer 1

And after all, when you have the available Update Target button and the disabled Generate Script button.

See if your source is a database and your target is your SSDT project.

If so then click "Switch source and target" button.

The Generate Script button will become available.
I.e. a SSDT project must be the source and a database must be the target in the Schema Compare window.
