See you at TechEd! I'm giving DEV389.
I'm confirmed to speak at TechEd 2003 in Dallas in June. I'm going to give a mid-level talk about XML Web Services with WSDL as the fulcrum. I'll talk about the need for a contractual agreement to exist between business entities and computers. I'll walk up the conceptual stack, transport, syntax/structure, semanetics via rich types, business messages, and end points described with WSDL. I'll do a lot of sniffing and looking at SOAP on the wire, and explore proxy generation with XSD.exe and WSDL.exe. Probably I'll spend a lot of time at the command-line and jumping between 4 or 5 different tools that AREN'T Visual Studio. It's nice to point out at towards the end of the talk that we have been moving seemlessly between XML tools (many not from Microsoft), creating, editing, generating schemas, making WSDL, generating proxy code. It's a nice reminder to the people in the audience who STILL haven't used Web Services that there ARE standards around this stuff! And while all standards evolve, in this case the wire protocol is transparent.
