AuthenticationResult result = null;
int retryCount = 0;
bool retry = false;
string header = "";

do
{
    retry = false;
    try
    {
        
        result = authContext.AcquireToken(todoListResourceId, clientCredential);
        header = result.CreateAuthorizationHeader();
    }
    catch (AdalException ex)
    {
        if (ex.ErrorCode == "temporarily_unavailable")
        {
            retry = true;
            retryCount++;
