Attachments to Tables Not Supported

Table support has definitely improved with the release, but support for attachments to tables (i.e. no geometry) isn't quite there yet.  A ServiceFeatureTable indicates that it has attachments, but QueryAttachmentsAsync causes the following exception:


A first chance exception of type 'System.Exception' occurred in mscorlib.dll

Not found : Row not found.

   at RuntimeCoreNet.Interop.HandleException(Boolean retVal)

   at RuntimeCoreNet.CoreFeatureSource.ImportAttachmentInfos(String jsonFilePath, Int64 featureID)

   at Esri.ArcGISRuntime.Data.ServiceFeatureTable.<ImportAttachmentInfosAsync>d__42.MoveNext()


An offline geodatabase indicates that the table has no attachments, and the attachment tables are not present in the geodatabase (although they are for a feature class), so that looks like an ArcGIS Server 10.2.2 issue.
