    Hi Dave,

    the code looks absolutely correct.

    To answer your question, could you provide some information about how the
    one-to-one is mapped. Is it PK-> dep. PK? If so, is the corresponding
    checkbox checked on DbRelationship from Employee to RetirementAccount?

    Details of your db schema for these 2 tables will help too.
