Instructor Notes
Now it's time to talk about how WSS V3 layers on top of the ASP.NET Web Part infrastructure.

First, point out that Web Part customization data needs to be written not to the ASP.NET services database but to the content database of the hosting WSS site. For this reason, the WSS team was not able to directly use the WebPartManager control or the WebPartZone control. Instead these used these classes as base classes and dirived two specialized class named SPWebPartManager and SPWebPartZone.

One of the main reasons to point this out to students is that Web Part pages contain WebPartManager and WebPartZone from an ASP.NET application cannot be used inside a WSS site unless it is modified to use SPWebPartManager and SPWebPartZone.

Finally, mention that the SPWebPartManager is placed on default.master so that it doesn't need to be placed on content pages.
