Getting this error "An exception of type 'Microsoft.OneDrive.Sdk.OneDriveException' occurred in mscorlib.dll but was not handled in user code" in below code... I am building a console App...

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using Microsoft.Azure.ActiveDirectory.GraphClient; using Microsoft.Azure.ActiveDirectory.GraphClient.Extensions; using System; using System.Collections.Generic; using System.Threading.Tasks; using Microsoft.OneDrive.Sdk;

       calling();

    }

    static async void calling()
    {
        var oneDriveClient = BusinessClientExtensions.GetActiveDirectoryClient(
                    clientId,
                    returnUrl,
                    oneDriveApiEndpoint,
                    serviceResourceId);

        try { 
        await oneDriveClient.AuthenticateAsync();
    }
    catch(Microsoft.OneDrive.Sdk.OneDriveException e)
        {
            Console.WriteLine(e.Error);
            Console.ReadLine();

        }
        var drive = oneDriveClient
                                  .Drive
                                  .Request()
                                  .GetAsync();
        var rootItem = oneDriveClient
                         .Drive
                         .Root
                         .Request()
                         .GetAsync();

        Console.WriteLine(rootItem);
        Console.ReadLine();
    }
}

}

Can you please help me on this?

You are calling an async method in Main() without telling that method to run synchronously. The SDK is not compatible with that. Try checking out this StackOverflow thread about the topic.
