I'm trying the vision api for handwritten text recognition using C# with the mentioned code in Git. I face the below error at line Task.WhenAll(t1, t2).Wait(5000); Please suggest.

Are you using the ComputerVision 3.2.0 NuGet package?

[sandrapavankumar]

Yes, I'm using Computer Vision library 3.2.0 NuGet package.

Are you getting any output in the command window?

[easyj2j]

Are you getting any output written by the program?

[sandrapavankumar]

The output message is "Images being analyzed ... " and followed by an exception.

[easyj2j]

Would you attach your Program.cs file without showing your subscriptionKey?

[sandrapavankumar]

PFA.. program.txt

[easyj2j]

Leave the Endpoint as it shows in the example. The client library tacks on the service and v#.

computerVision.Endpoint = "https://westcentralus.api.cognitive.microsoft.com";

[sandrapavankumar]

I still face the same issue.

[easyj2j]

Your program works correctly when I run it. Is it possible that your subscription key is associated with a different region than westcentralus?
