If I'm not mistaken, Legend isn't supported for a DictionaryRenderer. Try calling _myFeatureLayer.GetLegendInfosAsync() and see if it returns anything.

I'm curious: Does it work if you instead of using *, add all the missing field names to the list? I'm curious if it's a bug wrt using *, or if the data just isn't being made available for whatever reason.

Nice catch. This is actually a bit of an oversight and should have been publicly settable from subclasses. I'll log an internal bug. For now, here's a totally unsupported way to achieve it using reflection. This may or may not work in the future (tested on 200.8 but should likely work on older versions too): private void SetAttribution(string attribution)
{
var field = typeof(Esri.ArcGISRuntime.Mapping.ImageTiledLayer).GetField("_coreReference", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
var method = field.FieldType.GetMethod("SetAttribution", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.Public);
method.Invoke(field.GetValue(this), new object[] { attribution });
}

Also make sure you target `net8.0-windows10.0.19041` or higher with the explicit windows version in the target framework. A new WPF project typically just specifies `net8.0-windows` which is equivalent to Windows 7. We require at least `10.0.19041`. Btw you don't need to install `ArcGIS_Maps_SDK_DotNet_200_7_0.vsix`. That just gives you a local nuget repo of the packages (for offline scenarios), but they are on nuget.org so they'll just pull from there instead.

Since we haven't been able to reproduce, there hasn't been any progress. If you have a reproducer you can share, I'll be more than happy to take a look.

The default callout, no, but you can instead use the overload that takes a UI Element, and put whatever user-control you want inside it: https://developers.arcgis.com/net/api-reference/api/netwin/wpf/Esri.ArcGISRuntime.UI.Controls.GeoView.ShowCalloutAt.html#Esri_ArcGISRuntime_UI_Controls_GeoView_ShowCalloutAt_Esri_ArcGISRuntime_Geometry_MapPoint_System_Windows_UIElement_System_Windows_Point_

No the anchor is only to a certain location, and not scaling. > Is this a feasible plan, given we will have a few hundreds of devices on the map as graphic overlay ? This will definitely give you performance issues. The feature is meant for minor set of elements like callout to be placed at a location. For high performance rendering you really need to be rendering with the existing layer types - XAML just isn't geared for that kind of dynamic rendering. You could look into the raster layers which allows you to place raster images that'll scale with the zoom.

You will need to set the ViewOverlayAnchor attached property on your view element so the mapview knows how to position it. Example: GeoView.SetViewOverlayAnchor(myCheckBox, new MapPoint(-117, 34, SpatialReferences.Wgs84)); See the doc here: https://developers.arcgis.com/net/api-reference/api/netwin/winui/Esri.ArcGISRuntime.UI.Controls.GeoView.Overlays.html#Esri_ArcGISRuntime_UI_Controls_GeoView_Overlays and here: https://developers.arcgis.com/net/api-reference/api/netwin/winui/Esri.ArcGISRuntime.UI.Controls.GeoView.ViewOverlayAnchorProperty.html

oh wait I forgot we do expose the GeoViewHolding event already. You can use that to set a flag that the user is currently holding / magnifier is showing, then use the pointer-up event to drop the pin.

> I am looking at the swift SDK. And it looks like swift has events that do not exist in .net. The events are provided by the underlying platform views. For .MAUI that could be done via the gesture recognizers but doesn't look like they currently expose a holding event. In the maps sdk, it's actually done at the lower native level (UIKit on iOS, View on Android and FrameworkElement on Windows), and relies on the holding event to start showing the magnifier, and the pointer-up for turning it off. So you'd need to use a combo of those two events for your scenario.

@ShaneRumbaugh Could you share a little bit about the scenario that you need the image for? I can add your specific user-story to our internal issue tracking this feature request so we make sure it'll cover your case too.

Have you considered using the ShowCalloutAt method instead? This will host your UI element and move it around to keep it on top of the map. A more advanced method would be to create a custom control yourself to host your content, and have that implement IViewOverlay interface, which will give you the information needed to re-arrange the view yourself (this is also what the callout uses to do this).

Btw the specific error you're getting should only happen if you've used features that requires a license before you attempted to license the application.

Once your app is licensed, you can only license "up", ie license for a higher-level license. There's no way to re-license the application without restarting.
