New Post: PropertyDescriptor doesn't work for PropertyGrid in community edition?

I need dynamic object binding to PropertyGrid control, so I created a class that inherits PropertyDescriptor, but the only properties/methods gets called are NameHashCode and PropertyType.

GetValue, SetValue, IsReadOnly or any other - never gets called. What am I missing here? So I tried different approach:

var cpi = new CustomPropertyItem();
// set cpi properties as needed...
MyPropertyGrid.Properties.Add(cpi);

But I get compilation error (cannot access CustomPropertyItem's internal constructor).

So what's going on? these features are blocked in the community edition or something like that?
