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/ArcGISRuntimeSamplesDe..., 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.
