Jim posted an intro walkthrough on using Windows Azure Table Storage. If you're looking to get your head around using Windows Azure Tables, its the simplest way to get a sample up and running on Windows Azure that uses Table Storage Service. Although there’s a wealth of information on Azure. To be clear, this post isn’t comprehensive or trying to dive deep in technology, it just serves as an introduction to how Table Storage Service works. Also, take a look at Quick Lap Around the Tools before this walkthrough. After you’ve completed this walkthrough, you’ll have a Web Role that’s a simple ASP.NET Web Application that shows a list of Contacts and allows you to add to and delete from that list. Each contact’ll have simplified information: just a name and an address (both strings).
