I recently had troubles Importing a Database from a SQL Server Database Project in VS 2015. Just hoping this helps some folks. I will add more pictures when my rep is higher.
Error I get: The server version or database compatibility level is not supported.
This is the Error I get when I right click on the project and try and Import a Database. Import Error:
Right click on the Project and clicking View in Object Explorer.
Add and connect to your database next, if needed. Right click on the database you are wanting to import and click Create New Project.
Change settings if needed. Then Click Start
