Your needs are perfectly served by Entity Framework[^]. I suggest you switch to EF.

Than it is your duty as developer or as architect to present the drawbacks of it. By the way EF is ADO.NET technology. Or you can mimic the working way of EF by constructing the object yourself, loading the main entity data and the referred data too, with whatever you like.
