THANK YOU

...unrelated issues can cause VS to incorrectly parse the page and give this error...

That was the secret...I plowed through the forest of error messages and low and behold one jumped out that was unrelated. I still had the links in my development web.config for some playing I had done with the release of the .Net 3.5 Data Visualization component - which of course is now a core part of the .Net 4 framework and in the GAC.

I removed the tagprefix configuration for:
<add assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" namespace="System.Web.UI.DataVisualization.Charting" tagprefix="asp">
And magically everything is compiling again!

Good catch.
