Seems like the easiest thing would be to have the ability to control
when the dirty flag is set. For example, in the setter of my binary
object, I could just set isdirty was true, and have nHibernate just
check my own bool dirty flag.
Otherwise...I'm not sure what you mean by user type. Are you saying I
should do something like this:
Thing
{
public virtual Id {get;set;}
public virtual MyCustomBinaryData {get;set;}
}
class MyCustomBinaryData
{
byte[] Date {get;set;}
}
thanks for your help with this!
