Hello and thanks for your help in advance.

I am starting on the NHibernate world and i am experimenting with the NHibernate CookBook recipes, i am trying to set a base entity class for my entities and this is the C# code for this. I would like to know whats the VB.NET version so i can implement it in my sample project.

This is the C# code:

public abstract class Entity<TId>
{
 public virtual TId Id { get; protected set; }

 public override bool Equals(object obj)
 {
 return Equals(obj as Entity<TId>);
 }

 private static bool IsTransient(Entity<TId> obj)
 {
  return obj != null &&
  Equals(obj.Id, default(TId));
 }

 private Type GetUnproxiedType()
 {
  return GetType();
 }

 public virtual bool Equals(Entity<TId> other)
 {
   if (other == null)
   return false;
   if (ReferenceEquals(this, other))
   return true;

   if (!IsTransient(this) && !IsTransient(other) && Equals(Id, other.Id))
   {
    var otherType = other.GetUnproxiedType();
    var thisType = GetUnproxiedType();
    return thisType.IsAssignableFrom(otherType) ||
    otherType.IsAssignableFrom(thisType);
   }
   return false;
 }

 public override int GetHashCode()
 {
   if (Equals(Id, default(TId)))
   return base.GetHashCode();
   return Id.GetHashCode();
 }
}  

I tried using an online converter but puts a Nothing reference in place of default(TId) that doesn't seem right to me that's why I request for help:

 Private Shared Function IsTransient(obj As Entity(Of TId)) As Boolean
        Return obj IsNot Nothing AndAlso Equals(obj.Id, Nothing)
    End Function

I Would appreciate the insight you may give me on the subject.
