Mock.As appears to be broken in Moq 4.1.1308.2321

[TrevorPilley]

The following works as expected in 4.0.10827 but in 4.1.1308.2321 the foo as IDisposable cast doesn't succeed.

public interface IFoo
{
    void Bar();
}

[TestFixture]
public class Tests
{
    [Test]
    public void Test()
    {
        var mock = new Mock<IFoo>();
        mock.Setup(x => x.Bar());
        mock.As<IDisposable>().Setup(x => x.Dispose());

        Action<IFoo> testMock = (IFoo foo) =>
        {
            foo.Bar();

            var disposable = foo as IDisposable;

            if (disposable != null)
            {
                disposable.Dispose();
            }
        };

        testMock(mock.Object);

        mock.VerifyAll();
    }

This was an unintended break from pull request #4.

I'm working on a fix. For the time being, if you move the .As to be the first line right after creating the mock, this test passes.

Will keep you posted.
