I was evaluating SF and the samples go well, but I buy it and uninstall the demo version and install the new one. Now the BO does not appears in the samples, when I create a new project does not appears too, I build it but does not appears in the toolbox.

If you still can't see your BOs in the toolbox, let us know.
