Did you also upgrade your customizations? In order to be able to debug your
customizations, you will need to re-DAG any assemblies you created in the
previous version of Visual Studio then re-reference them in your Visual
Studio 2008 project. Also make sure that your project is set to Debug mode,
not Release mode.
Follow the instructions outlined in the first chapters of the Visual Studio
Tools manual to upgrade your customizations.
