Working thru the book samples my class successfully created content pages and everything was fine with the masterpage. They are now creating their own pages using the book pages as examples.

Locally, their code works fine, but when we move it to an IIS server we get a wierd error, "MasterPageFile attribute is not supported by the page directive." It's exactly like the samples, and certainly seems like it has to be there to tell the pages what master file to pull in.

Is anyone else seeing anything like this? Thanks!

This turned out to be an issue of the compiler referring to a .net v1.1x folder which we could not eliminate. Used the aspnet_regiis.exe command to repair IIS mapping and specify the v2.0 folder. Further commands let you re-register the aspnet_isapi.dll, but I did't have to go that far.
