As Nick has mentioned we’ve released a Getting Started guide for the Windows Live Tools for Visual Studio controls. The November CTP (details here, download here) has a bunch of controls for implementing Live Services in your web apps.
It includes ASP.NET controls for Contacts, Login status, Maps, Messenger chats, Silverlight streaming etc. The November CTP includes compatibility with Windows Azure and was upgraded for Silverlight 2.0.
The Getting Started guide is 53 page PDF and is available for download via pZing. It covers all the basics plus a few cooler techniques you might otherwise miss. Simply click on the image to the right to download it. Enjoy.
