>     [Test, Timeout(10_000)]
>     public void TestCreateMultipleSessionsFromDifferentThreadsWhenConnectionNotStarted()
>     {
>         Connection = CreateAmqpConnection();
>         Assert.NotNull(Connection);
>         Parallel.For(0, 10, i =>
>         {
>             ISession session = Connection.CreateSession();
>             Assert.NotNull(session);
>         });
>     }
