Ok so how do I get the description to show up on a property with intellisense?

Here is what I have:

Code:
Private ld_PropName as string

<Category("Cat"), Description("I want to see this in Intellisense.")> _
    Public ReadOnly Property PropName() As String
        Get
            PropName = ld_PropName
        End Get
    End Property
Nothing, nada, nil, zip, zilch in intellisense for description. Any ideas??

Thanks all,

D
