I am trying to connect to postgres database running on docker container from visual studio, I am sure the DB exists and here is the logs:

docker ps:

docker ps
CONTAINER ID   IMAGE      COMMAND                  CREATED          STATUS          PORTS                    NAMES
a84a2dabf8a6   postgres   "docker-entrypoint.s…"   10 minutes ago   Up 10 minutes   0.0.0.0:5432->5432/tcp   catalogdb

My connection string:

 "ConnectionStrings": {
    "Database": "Server=localhost;Port=5432;Database=CatalogDb;User Id=postgres;Password=postgres;Include Error Detail=true;"
  }

inside docker container:

postgres=# l

(4 rows)

the error:
Npgsql.PostgresException (0x80004005): 3D000: database “CatalogDb” does not exist

I try to connect postgresql Db from visual studio to existing Database but got database does not exist error. How can I connect to psql db running on docker container from visual studio.
