Come hear an overview of the REST principles and why REST is becoming popular beyond traditional Web applications. Learn how to write applications that produce and consume RESTful services using the .NET Framework 4 and the improvements we have planned for future versions of the .NET Framework.

This session is a survey of implementing BlazeDS with your Flex applications. You will get a good mix of discussion and code, so at least you stay awake. BlazeDS is the server-based Java remoting and web messaging technology that enables developers to easily connect to back-end distributed data and push data in real-time to Adobe® Flex® and Adobe AIR™ applications for more responsive rich Internet application (RIA) experiences.

Come see how to build a continuum of client applications including HTML, AJAX, ASP.NET, Microsoft Silverlight, and Windows Presentation Foundation (WPF) that all consume the same Windows Communication Foundation (WCF) service. Learn how to reuse as much code as possible, how to optimize the development process, and how to address key logistical issues like external servers and cross domain communication.

Learn how to keep your customers, management, and quality assurance team happy by building testable Silverlight applications. Explore how the Model-View-ViewModel (MVVM) and Inversion of Control principles can be used with .Net RIA Services to create Silverlight applications with high testability across multiple tiers. Hear guidance from the Silverlight team on how to best use the available testing tools and technologies to take full advantage of your improved application designs to boost quality.

Learn how Web developers can use “M”, a new language for describing data, metadata and domain specific languages, to enhance RESTful services like HTTP, JSON, RSS/Atom, and more. Also see how “M” can be used on premise or in the cloud to achieve greater development productivity and to create more compelling customer experiences.
