Dr. WPF is truly dedicated to the advancement of WPF (or, as she/he calls it, “the greatest client platform known to geekkind”). The doctor has had a full time gig working with Avalon (that’s what WPF was called back when it had a cool name) since 2002
You can read Dr. WPF’s technical ramblings in this corner of the blogosphere and often in the WPF Forum. The doctor loves to defend the platform, criticize its shortcomings, argue the benefits of the developer/designer workflow, refer to silverlight as “the iridescent thong”, and solve really tough problems in very elegant ways using the power of WPF. If asked what makes WPF so cool, the homily that follows will usually include phrases like “data driven UI”, “rich property metadata”, “lookless control model”, “two-pass layout cycle”, and “routed events and commands”.
Not much is known about the person behind the persona, but if Brownie is to be believed, Dr. WPF is a man who looks something like the character to the left. Dr. WPF maintains that the actual person is much less interesting than the persona.
