The following test case is still printing incorrect results.

using System;
using System.Collections;
using System.Collections.Generic;

class App
        public static void Main (string[] args)
                foreach (object o in QueryEnumerable<string>())
                        Console.WriteLine (o);

        public static IEnumerable QueryEnumerable<T> ()
                Console.WriteLine ("Type 1: " + typeof(T));
                yield return (T) TestType (typeof(T));

        public static object TestType (Type t)
                Console.WriteLine ("Type 2: " + t);
                return null;

It prints:

Type 1: System.String
Type 2: 0

while it should print:

Type 1: System.String
Type 2: System.String
