Test case showing mono .NET difference

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.5
(KHTML, like Gecko) Chrome/4.0.249.43 Safari/532.5

On .NET calling (the non static method) TreeNode.Clone() returns a object -
which (runtime) type is the same time as the derived class.

IE for class MyTreeNode:
class MyTreeNode : TreeNode {}

var n = new MyTreeNode();
n.Clone().GetType() would equal MyTreeNode on .NET but equals TreeNode on mono.

Reproducible: Always

Steps to Reproduce:
1. Compile and run attached test case.
Actual Results:  
CloneTest.MainClass+MyTreeNode
System.Windows.Forms.TreeNode

Expected Results:  
CloneTest.MainClass+MyTreeNode
CloneTest.MainClass+MyTreeNode
