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.

For many, building large scale service based systems equate to using SOAP. There is, however, another way to architect service based systems by embracing the model the web uses – REpresentational State Transfer, or REST. .NET 3.5 introduced a way of building the service side with WCF – however you can also use ASP.NET’s infrastructure as well. In this session we talk about what REST is, two approaches to creating REST based services and how you can consume these services very simply with LINQ to XML.

In this presentation filmed during QCon London 2008, Christian Weyer, co-founder of thinktecture, explains how to create distributed systems using SOAP or REST on top of Windows Communication Foundation (WCF) or Windows Workflow Foundation (WWF).
