C# - Create A Visual-Studio String Visualizer?

I was trying to create a visualizer for IDictionary or ICollection Then like the simple visualizer (without dialog; I mean the ususal string visualizer that appears when hovering the variable, see image below), I want to make my custom text, I want to cast the collection to its type's list (I.E. StringCollection to List(Of String) or List) and then I will be able to see it in the visualizer. Or for Dictionaries show to lists visualizers for keys and for values.how to implement or even how to start?This is something I thought about:

using System.Collections.Specialized;
using System.Collections;
namespace ConsoleApplication2
{

[code]....

I want to use something similar for ICollection (or IList), IDictionary etc.Note that in arrays, the visualizer shows every nested objcet.This is actually what I want to achieve:Try to visualize a List and you will see that there is a private value _items, so you can see its items. I want to achieve something similar in collection and dictionary.
