title: .NET RIA Services and Custom Data Model - CRUD Capabilities
body: <p>I would like to ".NET RIA Service"-enable my custom data model (BLL/DAL).  Are there interfaces I have to implement to enable this functionality or all I have to do is create a Domain Service?  If so, how can tell my Domain Services about my BLL?  For Astoria, one has to implement IQueryable and IUpdatable interfaces for CRUD capabilities.  Is this the same for RIA Services?</p>
