EDM databinding using BindingSource?

[Edward]

Does EMD support design time databinding, except edmx designer itself?

For example, I can add SQL Server data source from Data Sources pane and
then drag&drop to a Form to let IDE automatically create controls for me.

How can I do this with EDM?

Create your Datasource(s) from your emd entity *objects. The datasources
defines the "shape" of your data.
Then fill your Bindingsource(s) via code as normal (i.e. linq, etc)
