I'm doing my first test asp.net3.5 app using EntityDataSource. I've got the basic project built and the Entity model created and compiled. Database is a local sqlexpress one in app_data directory.

When I put the <asp:EntityDataSource /> control on the page and try to configure it, I'm getting the message "The list of named connections could not be loaded because the configuration could not be opened".

At this point, everything in the project is "auto-created" by Visual Studio 2008sp1.

I confused as I cannot find any information on how to correct from this message.
