c#, EF, Code First, Repository Pattern and One-to-One relationships

Hi,

Could somebody help me please, I'm not understanding the repository pattern very well!

I have a model whereby I have a Person entity with a one-to-one link with a PersonProfile Entity.

So I have my two entities:

public class person
{
    public int PersonId {get;set;}
    public string Name {get;set;}
    ....
    public int PersonProfileId {get;set;}
    public virtual PersonProfile PersonProfile {get;set;}
}

public class PersonProfile
{
    public int PersonProfileId {get;set;}
    ....
}

I have a repository for Person and a service for creating the person.
Now I need to make sure that whenever a Person is create a Personprofile is also created and linked (with blank data in it). The idea being prevent me having to check further down the line that the records exist before I try to update or display them.

But how would be best to do it? Create a personprofile repository and send through a reference when I call the create person service? Do it from my controller page and make sure it's all hooked up before I pass the object to the person create service?

i.e.

personprofile profile = new person profile();
personprofileservice.create(profile);
personprofileservice.save();

person person = new person();
person.personprofile = profile;
personservice.create(person);
personservcice.save();

Or is there a better way I'm not just not understandng?

Thanks in advance.
