If you are unit testing a method that gets an Arranged mocked property and, then, sets that property, how do you verify the results at then end?

For example, let's say we want to unit test a method that looks like:

public void MyMethod()
{
    if (_view.SelectedObject != null)
        _view.SelectedObject = null;
}

I would expect to be able to write a test similar to:

[TestMethod]
public void MyMethodTest()
{
    var view = Mock.Create<iView>();
    var testObject = new Thingy();
  
    Mock.Arrange(() => view.SelectedObject).Returns(testObject);
    Mock.ArrangeSet(() => view.SelectedObject = null);
      
    objectUnderTest.MyMethod();
  
    Assert.IsNull(view.SelectedObject); 
}

The assert fails because the mocked property return is still in effect and you get testObject.  What's the proper way to write this test?  Thanks!
