Graph API does not work in console app but works in UI app.

Question

Hi,

I am created an app using Graph API. I need to run the app as a Windows Form UI app and as a console app. I am using client credential flow. After setting up all required app permissions, my Windows Form UI app works fine. I can retrieve various data from Azure AD. But if I run the same code as a console app, it does not work. It stuck in the await GetAsync() statement. My code is like this:

     try {

           GraphServiceClient graphServiceClient = getGraphServiceClient();   

           var exuser = await graphServiceClient.Users[upn].GetAsync();

     }

      catch (Exception ex)

        {

            //exception handling here

            return false;

        }

This code is to check if a user has been synched from AD to Azure. If not, this code should throw "not found" exception. In UI mode, I do see exceptions caught. But in console mode, exceptions are not caught. Maybe exceptions are handled differently in UI mode and console mode?

Anyone can point me to where I should look into?

Hi @Chris Zohno

In SDK 5.0 and above, I recommend that you use OdataError instances to catch exceptions.

try
{
    var exuser = await graphClient.Users["******@xxxxxx.onmicrosoft.com"].GetAsync();
}
catch (ODataError odataError)
{
    Console.WriteLine(odataError.Error.Code);
    Console.WriteLine(odataError.Error.Message);
}

Hope this helps.
