MVVM: Views and ViewModels
wraps a simple data object (a DirectoryInfo in this case).
Notice passes a string (the key) and an object (the data). This service basically allows you to loosely couple various objects together – we’ll
see key and an object. In the previous post, I provided a link to the project template you can use to start

SOS: finding the method bound to an EventHandler with WinDbg.
I was preparing a sample memory leak application for an Advanced C# class at Microsoft this past week and debugging through it with SOS.DLL ("Son of Strike"). My prepared application was an ASP.NET application that would leak memory by holding references to the page objects after they had completed their work. This, of course, is bad form because the System.Web.UI.Page object is intended to
be I did this by having the page hook up an event handler to a global event and then never remove the handler.

Weak Observer
NET code that can often induce a memory leak. The typical case that is often presented is one where a Windows Form subscribes to an event from a different object say some application object. When the form subscribes to the event on the application object, the application object therefore has a strong reference to the form so that it can deliver the events. During a recent teach of Code Smarter for Design Patterns in .NET NET in which we teach the Observer pattern showing both traditional GOF implementation as well as a more appropriate .NET
