Accessing web services with SOAP can be just as easy as using REST with all the enterprise-class features you've come to expect from WSDL and SOAP. Who says that the cycle of metadata and proxy generation should be so hard? I gave a talk at the NOVA Code Camp 2008.1 that shows how by using the CodeDOM, and the ServiceModel.MetadataImporter, you can generate proxy code dynamically.
In this talk, I also showed how IronPython can be used to add a dynamic "lower edge" to a C# application to make it much more dynamic feeling. Finally, we finished with a discussion about features that may be added to Visual Studio 10 and the C# 4.0 language sprecification to make SOA achievable for many more developers. It was a lively discussion with lots of great questions. Here are the slides and the demo code:
ProxyGen20080517.zip (20.86 kb) - Sample code that demonstrates the use of IronPython and some custom CodeDOM code to avoid generating proxies for WCF integration via SOAP/WSDL. IronPython 2.0 Beta 1 or newer is required to compile this code.
