Nhibernate could not resolve property exception when using QueryOver, works on QueryAll

Question

I have the following problem
Basically I have the 2 snippets below:

var contactAssociation =
    session.QueryOver(() => c         


        

Answer 1

You need to specify a Join in the first query. The LINQ provider in the second query does it automatically for you.

session.QueryOver<ContactAssociation>(() => contactAssociationAlias)
   .Where(() =>
       contactAssociationAlias.Contact.ID == careGiverId &&
       contactAssociationAlias.Client.ID == clientKey)
   .JoinQueryOver(() => contactAssociationAlias.AclRole)
       .Where(a => a.RoleName == "Care Giver")
   .SingleOrDefault();
