Take the simpliest type:
 public class AdaptedOrder
        public string BuysPrice { get; private set; }

System.Windows.Forms.ListBindingHelper.GetListItemProperties(typeof(AdaptedOrder), null); on .net 4.6.2 returns PropertyDescriptorCollection with single element - BuysPrice.
the same code runing on mono 5 returns around 70 properties.

It feels that mono returns all the properties of the Type<Type>, not AdaptedOrder itself.

Please check ready-to-compile source code at the following link, you can find the output of the program there: https://github.com/altmind/TestListBindingHelperListItemProperties/blob/master/TestListBindingHelperListItemProperties/Program.cs

This bug effectively leads that GridViews are rended with all the cells empty on mono when using custom Datasource of IBindingListView(Such as http://blw.sourceforge.net/)

Just a sidenote, I was able to hack around this by copying ListBindingHelper from Microsoft sources, and using this ListBindingHelper instead of mono version, there is source code:
