Chapter 1, Getting Started, shows how to set up your development environment. It covers the basics of ensuring that Visual Studio 2010, the Silverlight Software Development Kit (SDK), and the Azure SDK are installed. The tools that can be of assistance will be mentioned, such as Expression Blend, LINQPad to SQL Azure, and the Azure Storage explorer.

Chapter 2, Introduction to Azure, gives an overview of Windows Azure. It covers what Azure is, how Microsoft abstracts away the entire infrastructure worries so that the business can just focus on creating the business logic instead.

Chapter 3, Hosting Silverlight Applications in Azure, teaches how to create a Visual Studio solution that contains both the Silverlight and the Azure Project. The basics of how to consume a Windows Communication Foundation (WCF) service, hosted on Azure from within Silverlight is shown, as well as the basics of creating an Azure account and deploying it.

Chapter 4, Using Azure Queues with Silverlight, introduces the Azure storage service and the role it has within the Azure platform. The rest of the chapter then focuses on introducing the Azure Queue service. A Silverlight application is built that uses queues to indicate that widgets should be built.

Chapter 5, Accessing Azure Blob Storage from Silverlight, explains Azure Blob storage. A Silverlight application is built that can interact with the Blob storage to display the photos. It introduces the Azure CDN (Content Delivery Network) and how it can be used to increase the application performance.

Chapter 6, Storing Data in Azure Table Storage from Silverlight, introduces Azure Table storage and how it compares to the relational databases. Concepts such as how to partition your data for scalability are introduced. A Silverlight application is built that uses Azure Table storage to publish news stories.

Chapter 7, Relational Data with SQL Azure and Entity Framework, introduces SQL Azure and how it can be accessed through Entity Framework. You will learn the basics of querying and selecting data from an SQL Azure, and how to expose this data through WCF services.

Chapter 8, RIA Services and SQL Azure, explains how SQL Azure and RIA Services are combined. Rather than writing WCF methods by hand, RIA Services will be utilized to simplify the application development. You will learn how to modify and create data from within Silverlight.

Chapter 9, Exposing OData to Silverlight Applications, explains how OData is an open standard for exposing data. Data exposed in this way is queryable across a number of platforms, such as Silverlight, JavaScript, iPhones, and so on.

Chapter 10, Web-scale considerations, discusses breaking your application into asynchronous components that assists with the scaling of your architecture. Techniques for globalizing your application by hosting in multiple datacenters around the world are also shown.

Chapter 11, Application Authentication, focuses on how to get standard ASP.Net authentication and roles working with an Azure application by storing it in SQL Azure. The Azure Access Control System is also introduced as well as the Federated Authentication.

Chapter 12, Using Azure AppFabric Caching to Improve Performance, explores what data caching is and how it can improve the performance of your application.

No prior knowledge of Windows Azure is assumed. However, a basic background in Silverlight is expected. The chapters and exercises have been written to allow completion regardless of current skills.

The first chapter will take you through configuring your computer to allow you to complete the rest of the book. As long as you have an Internet connection and a copy of Windows (Vista or later), you will be able to obtain everything you require.

This book would primarily be aimed at application developers who want to build and run Silverlight Enterprise applications using Azure Storage, WCF Services, RIA services, and SQL Azure. A working knowledge of Silverlight and Expression Blend would be required. However, knowledge of Azure would not necessarily be required since the book would be covering how to integrate the two technologies in detail.

In this book, you will find a number of styles of text that distinguish different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

A block of code is set as follows:

using System.ServiceModel;
namespace WebRole1
{
[ServiceContract]
public interface IHelloWorldService
{
[OperationContract]
string GenerateHelloWorldGreeting();
}
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

using System;
using Microsoft.WindowsAzure.ServiceRuntime;

namespace WebRole1
{
public class HelloWorldService : IHelloWorldService
{
public string GenerateHelloWorldGreeting()
{
var currentTime = DateTime.Now.ToLongTimeString();
var instanceId = RoleEnvironment.CurrentRoleInstance.Id;
return string.Format("Hello World! The server time is {0}. Processed by {1}", currentTime, instanceId);

}
}
}

New terms and important words are shown in bold. Words that you see on the screen, in menus, or dialog boxes for example, appear in the text like this: "Right-click on the Silverlight project HelloWorldSilverlightProject and select Add Service Reference. Click on Discover to allow Visual Studio to automatically detect the WCF service in the solution".
