 EFPersistenceManager.Metadata() generation backward with EFCore for NotMapped and JsonIgnore attributes

I currently have a DB backing property and an exposed FE property, using [JsonIgnore] and [NotMapped] respectively.

I've previously used breeze for this without issue (in a previous project), but the metadata is exactly inverted for which fields should exist on the object.  It does not create a property on the entity metadata for the [NotMapped] property, but does for the [JsonIgnore]
