I'm using HBM mappings. I've tried FNH but I want to learn the
"basics" so to speak before I start using FNH. My final solution went
like this
I managed to map StudentAddresses in Student with a filter. To get a
fake one-to-one property 'Address' in Student I made a property
'Address' that does:
Address {
get { return this.Addresses.First() }
Not the best solution perhaps, but it should work since there should
always be one Address now in Addresses.
