DebuggerDisplay ignored when showing collection of items

Lets say I have an object:

[DebuggerDisplay("Bar={bar}")]
public class Foo
{
    public String bar{get;set;}
}

When I have a single instance of bar the debugger correctly shows Bar="value of bar" but when I have a dictionary of Foos, the dictionary shows:

{[key, namespace.Foo]}

when I expand the kvp I get the expected debugger display string.

When I override ToString() in Foo and have a dictionary of Foo the dictionary shows:

{[key, Bar="value of bar"]}

According to the documentation, ToString() is only used for debugger display if a DebuggerDisplay Attribute doesn't override it...

How do I get the debuggerDisplay attribute to override the debugger string in enumerated situations in addition to single instances?

An elegant solution to this problem is to apply the DebuggerDisplay attribute to System.Collections.Generic.KeyValuePair<TKey,TValue> via AssemblyInfo.cs as follows:

using System.Collections.Generic;
using System.Diagnostics;

[assembly: DebuggerDisplay("[Key={Key}, Value={Value}]", Target = typeof(KeyValuePair<,>))]
