I have worked around this problem with the following code, If  CreateDynamicLayerInfosFromLayerInfos() fails, I Generate the DynamicLayerInfos one by one(This does not answer the question why the CreateDynamicLayerInfosFromLayerInfos() fails 😞 myDynamicLayerInfos = (TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer)).CreateDynamicLayerInfosFromLayerInfos()                     If Not myDynamicLayerInfos Is Nothing Then                         'MessageBox.Show("Layer infos OK")                         Dim sourceArray(myDynamicLayerInfos.Count) As DynamicLayerInfo                         myDynamicLayerInfos.CopyTo(sourceArray, 0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos = myDynamicLayerInfos                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray(0))                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray(1))                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray(2))                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray(3))                     Else                         myDynamicLayerInfos = New DynamicLayerInfoCollection                         Dim lms As New LayerMapSource                         lms.MapLayerID = 0                         Dim dli As DynamicLayerInfo                         Dim sourceArray2(19) As DynamicLayerInfo                         Dim myLayerDataSource As Esri.ArcGISRuntime.Layers.LayerDataSource                         For i = 0 To 19                             dli = New DynamicLayerInfo                             dli.Source = lms                             dli.ID = i                             myDynamicLayerInfos.Add(dli)                         Next                         myDynamicLayerInfos.CopyTo(sourceArray2, 0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos = myDynamicLayerInfos                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray2(0))                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray2(1))                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray2(2))                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0)                         TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray2(3))                         'MessageBox.Show("Layer infos Not OK")                     End If                 End If ...

Hi Mike,     Thanks for the quick reply. I am programming a Runtime 10.24 .NET WPF application for a client. They have a large Oracle Geodatabase with a SDE front end. The application is using the LocalServer functionality to access the Geodatabase layers via a map Package. (They do not have the licencing required to publish a map service). As a proof of concept we have been using a small .mpk file so that I could program all of the functionality needed in the App without connecting to the SDE (I don't have permission). Everything works well with this .mpk here is a link:   https://dl.dropboxusercontent.com/u/48200319/BDT_Test_AreaSmall.mpk The problem has come up when we changed the MapPackage to one that References the SDE. Link here: https://dl.dropboxusercontent.com/u/48200319/BDT_Test_AreaWithRasters.mpk The problem occurs when using the BDT_Test_AreaWithRasters.mpk problem 1: when I load the mpk with the code in the MyMapView_LayerLoaded handler commented out. All layers except for the 2 Raster layers show up in the Legend. (Of course no data is displayed as I don't have an SDE connection). So why don't the Raster layers show in the legend. If I leave the Rasters out of the MapPackage and have an SDE connection the data displays. problem2: I want to re-order some layers and in a different place in the code be able to change renderers on "ITLBackgroundData"(0). To do this I need to get the DynamicLayerInfoCollection using CreateDynamicLayerInfosFromLayerInfos(). This works fine when using BDT_Test_AreaSmall.mpk  but fails when using BDT_Test_AreaWithRasters.mpk Any thoughts would be appreciated. Cheers Trevor Here is some code that should reproduce the problem: Dim _localMapService As LocalMapService  'Global Variable Private Async Sub LoadBackgrounds() Try Dim mySpatialReference As Esri.ArcGISRuntime.Geometry.SpatialReference mySpatialReference = Esri.ArcGISRuntime.Geometry.SpatialReference.Create(3005) MyMapView.Map.SpatialReference = mySpatialReference Dim myEnvelope As Esri.ArcGISRuntime.Geometry.Envelope myEnvelope = New Esri.ArcGISRuntime.Geometry.Envelope(1070635.92, 499061.341, 1071988.61, 499115.4) MyMapView.Map.InitialViewpoint = New Esri.ArcGISRuntime.Controls.Viewpoint(myEnvelope) _localMapService = New LocalMapService("..\..\MapData\BDTData\BDT_Test_Area.mpk", 1000000, True) _localMapService.EnableDynamicLayers = True Await _localMapService.StartAsync() Dim arcGISDynamicMapServiceLayer As ArcGISDynamicMapServiceLayer arcGISDynamicMapServiceLayer = New ArcGISDynamicMapServiceLayer() arcGISDynamicMapServiceLayer.ID = "ITLBackgroundData" arcGISDynamicMapServiceLayer.ServiceUri = _localMapService.UrlMapService arcGISDynamicMapServiceLayer.IsVisible = True MyMapView.Map.Layers.Add(arcGISDynamicMapServiceLayer) Catch ex As System.Net.HttpListenerException MessageBox.Show(ex.ToString) End Try End Sub Private Sub MyMapView_LayerLoaded(sender As Object, e As LayerLoadedEventArgs) Handles MyMapView.LayerLoaded If e.Layer.ID = "ITLBackgroundData" Then If Not IsBusy Then IsBusy = True Dim myDynamicLayerInfos As DynamicLayerInfoCollection = (TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer)).DynamicLayerInfos If myDynamicLayerInfos Is Nothing Then myDynamicLayerInfos = (TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer)).CreateDynamicLayerInfosFromLayerInfos() If Not myDynamicLayerInfos Is Nothing Then MessageBox.Show("Layer infos OK") Dim sourceArray(myDynamicLayerInfos.Count) As DynamicLayerInfo myDynamicLayerInfos.CopyTo(sourceArray, 0) TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos = myDynamicLayerInfos TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0) TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray(0)) TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(1) TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray(2)) TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.RemoveAt(0) TryCast(MyMap.Layers("ITLBackgroundData"), ArcGISDynamicMapServiceLayer).DynamicLayerInfos.Add(sourceArray(1)) Else MessageBox.Show("Layer infos Not OK") End If End If End If End If End Sub ...
