Two different technologies. The BDP classes are based on ADO.Net and use 
.Net databinding. They know nothing about the VCL, specifically about 
TComponent, and so cannot be dropped on VCL forms or datamodules. VCL 
controls, although compiled to be usable under .Net, require 
TDataset/TDatasource classes to hook up to and know nothing about .Net 
databinding.

You can still use BDP, but there is more manual work - the BDP components 
must be created and configured in code instead of on a design-time surface. 
You can drop TListConnectors (under the DataAccess tab) which is a TDataset 
descendant you can hook a normal TDatasource and data-aware controls to, 
then at runtime, link its DataObject property to any .Net component that 
implements IBindingList (.Net Dataset, etc.).
