You can use MapView.MapBackground property. You can also set LineWidth to 0. MyMapView.MapBackground = new MapBackground() { Color = Colors.Yellow };‍‍‍ ... View more

It seems that cause here is setting MapView and Maps SpatialRefernce correctly. It is normally taken from the first layer but GroupLayer doesn't have one. Here is code that should work <esri:MapView x:Name="MyMapView"     LayerLoaded="MyMapView_LayerLoaded"> </esri:MapView>‍‍‍‍‍‍ using Esri.ArcGISRuntime.Controls; using Esri.ArcGISRuntime.Geometry; using Esri.ArcGISRuntime.Hydrographic; using System; using System.Diagnostics; using System.Windows; namespace HydragraphicLayersDemo {     public partial class MainWindow : Window     {         private HydrographicS57Layer _layer;         public MainWindow()         {             InitializeComponent();             // Force to use WebMercator which is normally taken from the first layer             var map = new Map()             {                 SpatialReference = SpatialReferences.WebMercator,                 InitialViewpoint = new ViewpointExtent(new Envelope(0, 0, 0, 0, SpatialReferences.WebMercator))             };             // Create hydrographic layer and set it to the layers collection             _layer = new HydrographicS57Layer()             {                 ID = "US1WCO1M",                 Path = @"C:\Temp\HydragraphicLayersDemo\HydragraphicLayersDemo\bin\Debug\us1wc01m\US1WC01M.000",             };             map.Layers.Add(_layer);             // Set map to view             MyMapView.Map = map;             // Zoom to the layer when the layer is loaded             ZoomToHydrographicLayers();         }         private async void ZoomToHydrographicLayers()         {             try             {                 // wait until all layers are loaded                 await MyMapView.LayersLoadedAsync();                 Envelope extent = _layer.FullExtent;                 // Zoom to full extent                 await MyMapView.SetViewAsync(extent);             }             catch (Exception ex)             {                 MessageBox.Show("Error occurred : " + ex.Message, "Sample error");             }         }         private void MyMapView_LayerLoaded(object sender, LayerLoadedEventArgs e)         {             if (e.LoadError == null)                 return;             Debug.WriteLine(string.Format("Error while loading layer : {0} - {1}", e.Layer.ID, e.LoadError.Message));         }     } } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
