I am trying to run the example from this article.https://msdn.microsoft.com/en-us/magazine/mt788620.aspx
I am getting a Client exception. I created the keys here https://azure.microsoft.com/en-us/try/cognitive-services/my-apis/
In the example, I am passing the api key to the VisionServiceClient. But how do I know which endpoint is my VisionServiceClient pointing? I think there are a few different endpoints depending on the test page
how do I Change the endpoint for my VisionServiceClient ?
