Building Services: .NET FX 3.5, SOAP, REST, and Beyond Most developers will be aware of various Microsoft technologies to help build SOAP services, the latest of which are WCF and WF in .NET FX 3.5, but there’s another world of services outside SOAP. Recently Microsoft has been very active in its support for, and use of, REST as a mechanism for implementing services. This event will cover recent and forthcoming technologies for building services with SOAP and REST, and we’ll explain REST for the uninitiated. Agenda: Session 1: The SOAP Story In this session we’ll do a lighting quick re-cap of what SOAP is, what specs surround it before looking at how far the SOAP programming model has come in Microsoft’s latest-and-greatest stack – Windows Communication Foundation (WCF) V3.5. We’ll talk about different approaches to building services and we’ll take a good look at the integration between WCF V3.5 and Windows Workflow Foundation (WF) V3.5 which opens up a whole new way of implementing services. Session 2: Time for a REST Web applications have evolved; using technologies like AJAX and Silverlight they have rich client-side code that wants to consume services, but they prefer JSON, “plain xml” and REST. In this session we’ll introduce REST for the uninitiated, and we’ll demonstrate some of the new and forthcoming technology that Microsoft has for working with REST: WCF 3.5, Web3S, Windows Live Data, and Codename “Astoria”.
