* Introduction
* Welcome
These notes are an introduction to Windows Phone development for anyone learning to program. They assume some knowledge of programming fundamentals, but they will teach you programming concepts in the frameworkof Windows Phone development.
These notes do not teach programming from first principles. I am going to assume that you already know how to write and run simple C# programs on a Windows PC.
* What you need to have before you start
All the development tools that you need can be downloaded for free from here:http://www.microsoft.com/downloads/en/details.aspx?FamilyID=04704acf-a63a-4f97-952c-8b51b34b00ce
If you have your own Windows Phone device you can use this to run programs if you become a registered Windows Phone developer. This is free for students, and also lets you sell programs that you have written in the Windows Phone Marketplace. However, to get started writing programs you don’t need to have a physical device, you can use the emulator that is supplied with thedevelopment tools.
Windows Phone 7
In this chapter you are going to find out about the Windows Phone platform as a device for running programs. You will learn the key features of the platform itself, how programs are written and also how you can sell your programs via the Windows Marketplace.
The Windows Phone hardware
In this section we are going to take a look at the actual hardware that makes up aWindows Phone. This is particularly important as we need to put the abilities of the phone into context and identify the effect of the physical limitations imposed by platform that it uses.
A Windows Phone as a computer
Pretty much everything these days is a computer. Mobile phones are no exception. When you get to the level of the Windows Phone device it is reasonable to think of it as acomputer that can make telephone calls rather than a phone that can run programs.
The Windows Phone device has many properties in common with a “proper” computer. It has a powerful processor, local storage, fast 3D graphics and plenty of memory. It also has its own operating system which looks after the device and controls the programs that run on it. If you have used a PC you are used to the Windows...
