I have a solution with two projects: one containing a report, and another for the objects.

The first one has a project reference to the second, and the objects are used within an ObjectDataSource component in the report from the first.

I open the solution, build the project with the objects, but the Data Explorer of the ObjectDataSource component in the first project with the report does not get automatically updated. I have to reconfigure the ObjectDataSource manually for the change to take effect.
