Thae Native Maps SDK is a different SDK built from the ground up, so you'll find that APIs are different and located in other namespaces, and since it isn't COM you'll find much less use of interfaces, and more use of concrete classes. Some tasks might also be accomplished in a different way. You'll find the geometry related classes in the `Esri.ArcGISRuntime.Geometry` namespace.

You can find the doc for the equivalent SpatialReference class here: https://developers.arcgis.com/net/api-reference/api/net/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Geometry.SpatialReference.html

When you say they don't load, what load errors do you see? (observe the errors coming from LoadAsync, or just look in the debug output window where load errors should also be written)

You're missing the nuget package that contains the MapView. You will need to add one of the following nuget packages (depending on the UI framework you use): Esri.ArcGISRuntime.Wpf Esri.ArcGISRuntime.WinUI Esri.ArcGISRuntime.Maui Esri.ArcGISRuntime.UWP

If you put a try/catch around the SetLicense call, will you get a better exception in the catch? I've seen some issues with Microsoft not always handling un-caught exceptions that well

Are you building for AnyCPU? Could you try explicitly building for x64 and turn off "Prefer 32-bit"? This changes the deployment of native libraries slightly which might improve the assembly loading.

Can you share the specific exception type, message and callstack?

Are you experiencing any nuget restore errors? Wrt target framework, it needs to be either net8.0-windows10.0.19041, net9.0-ios18.0, net9.0-android35.0 or net9.0-maccatalyst18.0 or newer. Especially note .NET 9 if you are targeting .NET MAUI, since Microsoft no longer supports .NET 8 on MAUI, .NET 9 has been required since 200.7 for those targets.

The API Key is only needed to access arcgis online services (like for example the default basemap styles). If you don't use these, you don't need an API key. You will need a license key though, but a free lite-license is available which might or might not be enough for your scenario. See License and deployment | ArcGIS Maps SDK for .NET | Esri Developer for more info on that

Are you able to try with 200.8 and see if that makes a difference? (even if you aren't able to permanently move to it, if there's a version it started working might help us narrow the issue down). A lot has changed in utility network support since 200.3

The back button should only show if you drill into sub-features like related features or utility network associations. If that's not the case, please log a bug in the toolkit repo.

Take a look at FeatureCollectionLayer / FeatureCollection for in-memory feature tables as well as just creating your own on on-disk Geodatabase using Geodatabase.Create and CreateTableAsync. This will allow you to store data in feature tables that you can render using a feature layer and apply cluster rendering to using the FeatureReduction property. Having said that, GraphicsOverlay also supports FeatureReduction.

In general you should use the new PopupElements, which will also help you get the attachments: var popup = new Mapping.Popups.Popup(feature); await popup.EvaluateExpressionsAsync(); var attElm = popup.EvaluatedElements.OfType<Mapping.Popups.AttachmentsPopupElement>().FirstOrDefault(); Have you considered just using the PopupViewer control from the toolkit for viewing? It'll support all the formatting specified in the popup-definition, or generate a default definition is one hasn't been defined. You can also see its entire implementation here for reference: https://github.com/Esri/arcgis-maps-sdk-dotnet-toolkit/tree/main/src/Toolkit/Toolkit/UI/Controls/PopupViewer

To add to Preeti's answer, ALL of the above code can be replaced with AuthenticationManager.Current.AddCredential(await OAuthApplicationCredential.CreateAsync(SERVER_URL, CLIENT_ID, CLIENT_SECRET)); When using an app credential added up front, there's no need for messing with server infos, oauth configs, credential callbacks etc. Just the above line before accessing your server.

I'm not entirely if you're saying the above log was with replacing with a new mapview on resume? If that's the case, could you try it with just leaving the mapview alone as in the original sample you shared? (it's fine that the map is blank - but I'd like to understand if something on your device is not triggering these lifecycle events, since the MapView heavily relies on these to resume rendering). I do find it curious so far that you are seeing destroy+create. That could be the root of how these devices behave differently. If you repeat this on a device that does work, do you see a version of mine or your log? Lastly what does "TextureView does some things" mean?
