Use a ChallengeHandler. This gets called by the framework when you send a request that requires credentials //I put this in the constructor of a class that manages services AuthenticationManager.Current.ChallengeHandler = new ChallengeHandler(CreateCredentialAsync); This method will get called when there is a request for a token from the server private async Task<Credential> CreateCredentialAsync(CredentialRequestInfo info) { try { _log.Info($"CHALLENGE ********** : {info.ServiceUri} ***********"); if ( info.ServiceUri == null ) return null; var credential = await AuthenticationManager.Current.GenerateCredentialAsync(info.ServiceUri, Settings.UserName, Settings.Password); _log.Info($"RETURN credential *********: {info.ServiceUri} ********"); return credential; } catch (Exception e) { _log.Error(e, e.Message); return null; } }   ...

@PreetiMaske As I noted, I found that the SymbolDisplay toolkit control lacked the ability to adjust the size.  This may have changed after 100.6.  Because of that issue, the control was not usable in my application.  Had it worked I would have used it ... View more

@PreetiMaske is correct although I have found it a tad more complex and it depends what you mean by palette, and what you are doing it in.  If your in WPF it is pretty straight forward because WPF does not have things going on behind the scenes to optimize. The basic approach is to create a Model that expose an ImageSource which can be bound to your palette in the DataTemplate.  The ViewModel would contain the ObservableCollection of that Model.  Which is bound to the list being used to display the palette. Then you have to get the ImageSource.  Something along these lines.  When the Model object is created the RuntimeImage is converted to an ImageSource.  Having a .Wait()  in the constructor is certainly not a best practice, but it is how I implemented.  Using something like a static  CreateAsync on the Model object is probably a better pattern   //this is the model - the item of the collection being bound public class SymbolItem public SymbolItem(LegendInfo legendInfo, ...) { LegendInfo = legendInfo; ... Task t = Task.Run(InitializeAsync); t.Wait(); } private async Task InitializeAsync() { //A little unclear on best way to adjust the parameters to get the image to size best RuntimeImage runtimeImage; if ( FeatureTable.GeometryType == GeometryType.Polyline ) { runtimeImage = await LegendInfo.Symbol.CreateSwatchAsync(24, 24, 128f, Color.Transparent, new Polyline(new [] {new MapPoint(-10, 0), new MapPoint(10, 0) })); } else { runtimeImage = await LegendInfo.Symbol.CreateSwatchAsync(24, 24, 128f, Color.Transparent, new MapPoint(0, 0)); } ImageSource source = await runtimeImage.ToImageSourceAsync(); //http://stackoverflow.com/questions/26361020/error-must-create-dependencysource-on-same-thread-as-the-dependencyobject-even source.Freeze(); Dispatcher.CurrentDispatcher.Invoke(() => ImageSource = source); } public ImageSource ImageSource { get; set; } ... }   In my ViewModel there is the ObservableCollection of these   public ObservableCollection<SymbolItem> SymbolItems { get; set; } = new ObservableCollection<SymbolItem>();   In Xaml I bind to the ImageSource   <!-- Would be nice to use this control, but have no control over image size with it --> <!--<esritoolkit:SymbolDisplay Symbol="{Binding LegendInfo.Symbol, Mode=OneTime}" Margin="0,0,5,0" />--> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="60" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Image Grid.Column="0" Source="{Binding ImageSource}" /> </Grid>   As noted there, the esri toolkit does have a SymbolItem but at least in 100.6 I found it did not provide enough control over sizing. In Xamarin Forms you have an added complexity in how it recycles images.  That required creating custom ViewCells to handle this issue... I won't go into that at this time   ... View more

To draw a shape based on user input you use the SketchEditor.StartAsyn method.  There is a simple example shown on the help page https://developers.arcgis.com/net/wpf/api-reference/html/M_Esri_ArcGISRuntime_UI_SketchEditor_StartAsync.htm   ... View more

ChallangeHandler gets triggered when credentials are required.  If you are already calling  IdentityManager.Current.AddCredential(cred); in code than credentials are not required and so the ChallengeHandler would not be called.  ChallengeHandler is a nice pattern to centralize all requests for credentials in a single place, and there is no need to specifically add credentials prior to accessing a resource ...

I am not sure if this is the same issue, or if it has been fixed in a later version of Runtime (we are still on 100.6).  But I have seen a timing issue with credentials.  It is discussed a bit here: Offline Map Sync Error: Job error 6004... I am not sure if this is related but was happening when I tried to sync soon after connecting the credentials had not been been applied to everything in my offline map.  So I got credentials errors.  Even though I set the credentials.   What I do to solve this is basically make a dummy hit against all layers before actually trying to do the real load of them. Basically I load a layer, don't worry if it gives me an error and then load the layer again and the second time the token has been properly applied.   /// <summary> /// This is used because of issue with the timing issues associated to /// getting tokens in first sync /// </summary> /// <returns></returns> private async Task InitialzeTokens(Map map) { if ( !_firstSync ) return; foreach (var featureLayer in map.OperationalLayers.OfType<FeatureLayer>()) { var pars = new QueryParameters {WhereClause = "1=0", MaxFeatures = 1}; if ( !(featureLayer.FeatureTable is GeodatabaseFeatureTable gdbFeatureTable) ) continue; if ( gdbFeatureTable.Geodatabase?.Source == null ) continue; var serviceFeatureTable = new ServiceFeatureTable(gdbFeatureTable.Geodatabase.Source); try { await serviceFeatureTable.LoadAsync(); var _ = await serviceFeatureTable.QueryFeaturesAsync(pars); } catch (Exception) { //_log.Error(e, e.Message); } } _firstSync = false; }   Also along the lines of what @JenniferNery describes.  Instead of doing   IdentityManager.Current.AddCredential(cred);   Use the ChallengeHandler and you can see when it requests credentials   //put in constructor AuthenticationManager.Current.ChallengeHandler = new ChallengeHandler(CreateCredentialAsync); private async Task<Credential> CreateCredentialAsync(CredentialRequestInfo info) { try { _log.Info($"CHALLENGE ********** : {info.ServiceUri} ***********"); if ( info.ServiceUri == null ) return null; var credential = await AuthenticationManager.Current.GenerateCredentialAsync(info.ServiceUri, Settings.UserName, Settings.Password); _log.Info($"RETURN credential *********: {info.ServiceUri} ********"); return credential; } catch (Exception e) { _log.Error(e, e.Message); return null; } }   Good Luck ...

I'm looking at the documentation for API Keys https://developers.arcgis.com/documentation/security-and-authentication/api-keys/ At the bottom there is a table which lists the services Available services Followed by, Access content and items (beta) Only ArcGIS Developer accounts can use API keys to read private content. ArcGIS Organization users should use OAuth 2.0 to obtain ArcGIS identity credentials to read private user content and access services on a user's behalf. They would need to figure out how to have licensing and the API key tied together.  My guess is that once they work out a plan it would have to go through an account manager to be all setup.     ...

Based on documentation it would seem the API Key is to allow monitoring of access to services, based on the ones described those are also services that are either free or charged on a unit basis.   Portal or AGOL require a licensed user (i.e., a user that has paid access).  The only way esri can validate that a user has payed access is if they are assigned a named user account.  If you just used the API key, how could esri track how many users are accessing the services for which they charge.  For offline uses you can have a license key for the application, but if you are online and want a resource, the user accessing that service needs to be validated ...
