Test project

The attached test project runs fine in .NET but produces a XamlParseException in Mono 3.0.10.

The exception occurs only if the class "Item" has a property with the same name as that of the derived class "Folder". The exception text is different whether or not the setter is public or internal.

IMHO the member should be ignored by XAML serialization because it is marked with [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)].

Here is the essential part of the code:

    public class Item
        public string Name { get; set; }

        public string Folder { get; internal set; }
    public class Folder : Item
        public Folder()
            Items = new List<Item>();

        public List<Item> Items { get; private set; }
    public class Root : Folder

The following XAML is loaded:
<Root Name='Test' xmlns='clr-namespace:TestObjectModel;assembly=TestObjectModel'>
  <Folder Name='Level1'>
    <Item Name='Item1' />
    <Item Name='Item2' />
