FAQ: VS Whidbey is not giving me

Becky pointed out Simon's comment on her blog. Unfortunately the new proxy generation features didn't make it into VS for Beta 1. They're currently only accessible through wsdl.exe. So if you use Beta 1's wsdl.exe to generate a proxy class you'll get properties not fields. You'll also get some other nice features such as type sharing across multiple proxies and event-based async programming model. See this for more info.
