Basically,you need to create your custom MetadataProviderFactory,which you plug in your module
model.RegisterContext(typeof(eDataContext), new ContextConfiguration()
{
ScaffoldAllTables = true,
MetadataProviderFactory = (type => new DefaultTypeDescriptionProvider(type, new AssociatedMetadataTypeTypeDescriptionProvider(type))),
});
