title: Does EF Core have a connection pool?
body: <p>The <code>DbContext</code> of EF Core is scoped in the ASP.NET Core services. So a new <code>DbContext</code> is created on each request. Does this mean that a new connection is opened on each request, including all the overhead like logging in to the database? Or is there a connection pool that is independent of the <code>DbContext</code>?</p>
