You have an invalid enpoint url ? You should use the endpoint url displayed in your azure account.

Something like this: https://westus.api.cognitive.microsoft.com/emotion/v1.0/recognize

Have used endpoint code too..

Can you post your endpoint?

Have used Key 2 as end point..

Have gone with Endpoint URL but its showing error message like this..

System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 40.112.254.71:443 at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception) --- End of inner exception stack trace --- at System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult, TransportContext& context) at System.Net.Http.HttpClientHandler.GetRequestStreamCallback(IAsyncResult ar) --- End of inner exception stack trace --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.ProjectOxford.Common.ServiceClient.<SendAsync>d__222.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.ProjectOxford.Common.ServiceClient.<PostAsync>d__202.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.ProjectOxford.Emotion.EmotionServiceClient.<RecognizeAsync>d__6.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.ProjectOxford.Emotion.EmotionServiceClient.<RecognizeAsync>d__5.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() at Microsoft_Cognitive_Vision.FormMain.<Camera_OnNewFrame>d__14.MoveNext() in C:\My Documents\SVN\Developer - Windows\ARC skill plugins\Microsoft Cognitive Emotion\Microsoft Cognitive Vision\FormMain.cs:line 166

Key2 is not the endpoint.

Look to the picture, you have Endpoint, Key1, Key2:

Questions:

1. Please post your endpoint url:

2. Can you reach internet from your desktop/ARC ?

Sorry to insist. I believe you are using the wrong endpoint url, go to your microsoft api account and use the endpoint url listed there.

Attention:

1. API keys are assigned per (Region) endpoint's url.
2. Some services are not available outside the selected geo location.
