Here is my working credentials code:

using (var stream =
    new FileStream("client_secret.json", FileMode.Open, FileAccess.Read))
    {
        string credPath = System.Environment.GetFolderPath(
            System.Environment.SpecialFolder.Personal);
            credPath = Path.Combine(credPath, ".credentials/calendar-dotnet-quickstart.json");

            UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                new string[] { CalendarService.Scope.Calendar },
                "username@gmail.com",
                CancellationToken.None,
                new FileDataStore(credPath, true)).Result;
            Console.WriteLine("Credential file saved to: " + credPath);
        }

Make sure to Enable the API in the Console,
