In the geekSpeak, Michele discusses timely topics in ASP.NET such as extending the ASP.NET profile service by appropriately using custom HttpModules to support dynamic implementation of master pages, application localization and more.  She goes on to discuss improvements to ASP.NET like the AJAX-programming paradigm with asynchronous access to data, and then the ASP.NET 3.5 extensions - new MVC, new ADO.NET data services libraries.

Michele gives her perspective on RIAs, including Flash, Silverlight, typical web applications and WPF (or rich client) - when to use which one from an architectural perspective.

She goes on to discuss SOAP vs. REST WCF services and the evolution of the programming model from raw SOAP message construction to REST-based calls which include wrappers and then onto JSON-based WCF services.  Next she shows the the ServiceHostFactory, and the WebScriptServiceHostFactory. She then presents the ASP.NET extensions ADO.NET data services (formerly Astoria). She concludes with an interesting discussion of when to use which type of service - SOAP or REST.
