Using `using`, am I understanding this right?

How does

using

using

differ between these two use-cases (haha, puns).

c#
using System;
using System.LINQ;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using Microsoft.EntityFrameworkCore.Sqlite;

c#
using System;
using System.LINQ;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using Microsoft.EntityFrameworkCore.Sqlite;

and

c#
using (var context = new Database_Load())`?

c#
using (var context = new Database_Load())`?

Ah ok I think I understand. So despite the same keyword usage, the importing namespace portion does not handle disposal at all? I think that is where I became confused is reading about the disposal for the second use-case and not understanding how it applied to the first.

These are two completely unrelated concepts

You can literally just pretend it says
