Last week at TechEd North America I did DEV303, Building RESTful Applications with the OData Protocol. I really enjoy doing this session since I get to code on the fly and talk about building applications. At a high level we covered:

• What is REST, comparison to Web Services (REST is resource based, Web Services is RPC/method based)
• What is OData, who is using it
• When to use OData vs RIA Services (OData is for exposing data as a service across boundaries, RIA is for a VB6 style RAD application development)
• Using WCF Data Services to build an OData Service
• Consuming the WCF Data Service in Silverlight asynchronously –yes everyone had to suffer and watch me code
• A Bill Gates joke
• WCF Data Services Service Operations, Data Interceptors (Query and Change), Data paging
• Consuming OData Services in ASP.NET (select and add, we even got to see my custom error raise)
