IT:AD:EF:ModelFirst

* Benefits: * Considerations:

• IT:AD:Code First offers more options to private set; and use logic than anything available via STE and T4.

• Benefits:
  • More productive than POCOs… * Considerations:
  • But in general, both ends have to be .NET (as the STE's change tracking internals are not serialized).
    See: Self Tracking EF4 Entities over WCF

STE's created by the T4 templates create entities that implement 2 contracts:

• IObjectWithChangeTracker
  • Defined inside the T4 Template.
• INotifyPropertyChanged
  • Defined in .NET 3.5 onwards (although changed directory).
