Forcing TLS 1.2 via System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12 and switching the project to .Net Framework 4.7 doesn't seem to help. ... View more

It does appear related to the authentication. I am using the code below.         Private ArcGISOnineUser As String = "xxx"         Private ArcGISOninePassword As String = "xxx"  Public Sub New()             Esri.ArcGISRuntime.ArcGISRuntimeEnvironment.ClientId = "xxx"             Esri.ArcGISRuntime.ArcGISRuntimeEnvironment.Initialize()             InitializeComponent()             IdentityManager.Current.ChallengeHandler = New ChallengeHandler(AddressOf CreateHardCodedCredentialAsync)     end sub    Private Async Function CreateHardCodedCredentialAsync(requestInfo As CredentialRequestInfo) As Task(Of Credential)             Dim cred As Credential = Nothing             Try                 Dim options = New GenerateTokenOptions()                 options.TokenAuthenticationType = TokenAuthenticationType.ArcGISToken                 cred = Await IdentityManager.Current.GenerateCredentialAsync(requestInfo.ServiceUri, ArcGISOnineUser, ArcGISOninePassword, options)             Catch webEx As ArcGISWebException                 ' couldn't generate a token, probably a bad login                   MessageBox.Show("Unable to log in to ArcGIS Online: " + webEx.Message)             End Try             Return cred         End Function After some investigation it seems that GenerateCredentialAsync never seems to return anything and the task seems to run indefinitely. as a test it tried having it wait for the task completion             Dim cred As Task(Of Credential) = CreateHardCodedCredentialAsync2("https://www.arcgis.com/sharing/rest")             Try                 cred.Wait()             Catch ex As Exception                 MsgBox(ex.Message)             End Try In this case it would just be stuck on cred.Wait() forever CreateHardCodedCredentialAsync2 is just there to replace the requestInfo.ServiceUri I tried running the sample in  https://github.com/Esri/arcgis-runtime-samples-dotnet/tree/10.2.7/src/Desktop/ArcGISRuntimeSamplesDesktop/Samples/Security/OAuthAuthorization, but when i clicked sign in all it did is display a page saying Invalid redirect_uri Error: 400 i left the default         private const string StandardAppDesktopRedirectUri = "urn:ietf:wg:oauth:2.0:oob"; as i don't have a landing page.and just filled in my client id. ...

I even tried using previous data that i used before for testing when it was working with the same issue. Here is the code                 Dim routeGraphics = TryCast(MyMap.Layers("RouteResults"), GraphicsLayer)                 If routeGraphics Is Nothing Then                     Throw New Exception("A graphics layer named 'RouteResults' was not found in the map.")                 End If                 Dim uri = New Uri("http://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World")                 Dim routeTask = New OnlineRouteTask(uri)                 Dim RouteRestrictions = New List(Of String)                 RouteRestrictions.Add("Avoid Toll Roads")                 Dim routeParams = Await routeTask.GetDefaultParametersAsync()                 routeParams.OutSpatialReference = MyMapView.SpatialReference                 routeParams.DirectionsLengthUnit = LinearUnits.Miles                 routeParams.ReturnDirections = True                 routeParams.DirectionsLanguage = New CultureInfo("en-Us")                 routeParams.FindBestSequence = CBool(OptOptimized.IsChecked)                 routeParams.PreserveFirstStop = CBool(PreserveStopsCbx.IsChecked)                 routeParams.PreserveLastStop = CBool(PreserveStopsCbx.IsChecked)                 routeParams.UseHierarchy = Not CBool(CbxAvoidHwy.IsChecked)                 If (CbxAvoidToll.IsChecked) Then                     routeParams.RestrictionAttributeNames = RouteRestrictions                 End If                 routeParams.ReturnStops = True                 routeParams.SetStops(routeGraphics.Graphics)                 Dim routeResult = Await routeTask.SolveAsync(routeParams) It gives that error on the last line ...
