Wow, a conference that lasts 8 days, that a first. So here’s the gist of what I taught in 5 of these days: What’s new in WCF 4.5 In this 1-hour session I covered some of the important new features of WCF 4.5, such as Intellisense for configuration, UDP and WebSockets bindings, and improved support for streaming and compression. Debugging the Web with Fiddler In this 1-day tutorial we saw how to use Fiddler to debug, test, and improve Web application. We saw how to work with the session list, use...

Trying to serialize EF objects with that serializer throws the following exception: "The type 'xxx' cannot be serialized to JSON because its IsReference setting is 'True'. The JSON format does not support references...
