Thanks a lot, about BelongsTo Unique,
if I want this situation:
public class Computer
{
....bla...
[HasMany]
public IList<InstalledSoftware> InstalledSoftware {get;set;}
}
public class InstalledSoftware
{
...bla...
[BelongsTo]
public Computer Computer {get;set;}
[BelongsTo(Unique=true)]
public Software Software {get;set;}
}
public class Software
{
...bla...
[Property(Length=300)]
public string Name {get;set;}
}
A computer can have many software installed, but obviusly not two same
software (I shouldn't reference 2 times SoftwareInstalled with same
software id). Should I handle it by myself or is ok written in this way?
Obviusly if I have a different computer, I can have same software
installed of another computer!!
