Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

Basic tenets

Does the design expect failures to happen regularly and handle them gracefully?
Have we kept things as simple as possible?

	public class TextBoxAttached : TextBox
	{


	#region ValidateOnTextChange (Attached DependencyProperty)

	public static readonly DependencyProperty ValidateOnTextChangeProperty =
	DependencyProperty.RegisterAttached("ValidateOnTextChange", typeof(bool), typeof(TextBoxAttached), new PropertyMetadata(new PropertyChangedCallback(OnValidateOnTextChangeChanged)));

	public static void SetValidateOnTextChange(DependencyObject o, bool value)
