Postgresql with Entity Framework 6 (first database approach)

Can I use EF6

with a database Postgresql

but using the first database approach? I found some solution that requires manual input of C # classes based on db structure, which is not satisfying for me. I would like to use it like Sql server

, so I select the server and database from the list, then I select the tables I want to use and voilà.

I installed npgsql

. I can add this database to the Server Explorer tab, but when I want to create an ADO.NET

Entity Model, I cannot find this database in the list.
