  • Artificial API: Removed MetaPersistentType.CreateEntityInstance method - The MetaPersistentType.CreateEntityInstance method is removed as it cannot support all cases of usage. The OpenAccessContextBase.CreateInstance method is recommended instead and can handle all scenarios.

  • Runtime: CreateDetachedCopies throwing an exception when L2 Cache is enabled - Currently the CreateDetachedCopies method is stable with L2 cache switched on.
  • Runtime: ObjectConstructed event and IInitializeCallbacks:InitializeTransients not called for collection items when L2 cache is used. - The ObjectConstructed event was not raised when an instance is loaded from the second level cache (L2C) and when the instance is retrieved as element of a reference collection, e.g. Order/OrderDetail.
  • Visual Designer: The IsManaged option for navigational members out of sync with the actual value in the OpenAccess metadata in some scenarios. - Currently the IsManaged option for the navigational members is always kept in sync with the OpenAccess metadata.
