Wpf binding not updating property

Abstract: The MVVM Light toolkit provides a lot of boiler plate code to implement Model-View-View Model based applications quickly and gives the user the freedom to customize and design the application.This article shows how to get started with MVVM development for WPF applications.How to handle them may vary, depending on what you're doing and what you're looking to accomplish, but WPF comes with two very easy solutions that you can use: The Observable Collection and the INotify Property Changed interface.

The second class is Essential Window, where you can set completely new look of the window.The problem is that none of the buttons seems to work. The first step is to get the UI to respond to changes in the list source (Items Source), like when we add or delete a user.What we need is a list that notifies any destinations of changes to its content, and fortunately, WPF provides a type of list that will do just that.The example is pretty simple, with a User class that will keep the name of the user, a List Box to show them in and some buttons to manipulate both the list and its contents.The Items Source of the list is assigned to a quick list of a couple of users that we create in the window constructor.So far in this tutorial, we have mostly created bindings between UI elements and existing classes, but in real life applications, you will obviously be binding to your own data objects.
