Slide deck: Web Parts in WSS v2, ASP.NET v2, and WSS v3.
Thanks again to Graham for asking us to present, the audience for showing up, and to Ali for co-presenting with me at the Metro Toronto .Net User Group last night.
It was a lot of fun to put together, as it's probably the first time that the instances of Web Part technology have been studied together as a real evolution. Now that the background is public knowledge (via the upcoming Whidbey RTM and SharePoint 2006 components announced at PDC), I was able to draw on presentations from both the ASP.NET PMs who baked the Web Part Framework into the web dev framework, and the SharePoint PMs who in turn made that work dance in SharePoint v3.
