ForeignKeyConstraintName for References

Hi Guys,

We're running the 1.0 RTM and mainly using AutoMapper.

My aim is to have the foreign key names look like so:
(For ManyToOne) (For OneToMany)

I've setup a convention for Foreign Key Constraints so like so:

public class ForeignKeyConstraintName : IHasManyConvention, IReferenceConvention

{
    public void Apply(IOneToManyCollectionInstance instance)
    {
        var keyName = String.Format("FK_{0}_{1}", instance.Member.Name, Inflector.Pluralize(instance.EntityType.Name));
        instance.Key.ForeignKey(keyName);
    }

    public void Apply(IManyToOneInstance instance)
    {
        var keyName = String.Format("FK_{0}_{1}", Inflector.Pluralize(instance.EntityType.Name), instance.Property.PropertyType.Name);
        instance.ForeignKey(keyName);
    }
}

The thing is: the OneToMany apply works fine, but the ManyToOne fails because it can't find the EntityType. There doesn't seem to be any properties on the IManyToOneInstance that can be used to get the table name the property is on.

Am I going about this the right way, and if sowhy is the EntityType comming up blank?
