Web Services, XML Serialization and Networking in .NET 2.0 (CTS2001)
I've just attended this session. Not so exciting, probably because I was already aware of many of the contents. The interesting thing is that it's confirmed the support for IXmlSerializable in .NET 2.0, even if the GetSchema method will be ignored by XmlSerializer, that instead will call a method defined through a new attribute called XmlSchemaProviderAttribute (something like [XmlSchemaProvider("MethodName")] on top of the class...).
We've also seen a demo of HttpListener class, hosting a Web Service using http.sys, on Windows XP SP2 (also available on Windows 2003, of course) in order to be able to host Web Services without IIS on the client side, for notification purposes for instance.
