Problem with non disposed disposables inside a using block

[BADF00D]

All these MemoryStreamCreations inside the using block should be marked as not disposed, like the second example shows.

[BADF00D]

All three MemoryStreams should be marked as not disposed.

using System;
using System.IO;

namespace DisFixerTest.ObjectCreation {
    class ObjectCreationInUsingBlock {
        public ObjectCreationInUsingBlock() {
            using(var memStream = new MemoryStream()) 
            {
                new MemoryStream(); //this should be marked as not disposed
                var tmp = new MemoryStream(); //this should be marked as not disposed
                var tmp2 = Create();//this should be marked as not disposed
            }
        }
        private IDisposable Create() {
            return new MemoryStream();
        }
    }
}
