Using CSOM, can I fetch RoleDefinitionBindings for all items in a list in a single query?

Question

I know I'm able to get RoleAssignments in my call to get a ListItemCollection, e.g.

context.Load(items, x => x.Include(y => y.RoleAssignments));

Is there a way to also load each RoleAssignments' RoleDefinitionBindings in the same call to the server? Can I extend the Includes in some way?

Answer 1

That one should do it:

context.Load(items, iCol => iCol.Include(
                item => item.RoleAssignments,
                item => item.RoleAssignments.Include(ra => ra.RoleDefinitionBindings)));
