Examples

This example shows a ComponentLoadFailedEventHandler. A loop iterates through the failed components. And RenewSystemComponentsAsync is invoked. Note that the RevocationAndRenewalInformation is passed in through the ComponentLoadFailedEventArgs.

private async void Manager_ComponentLoadFailed(MediaProtectionManager sender, ComponentLoadFailedEventArgs e)
{
    for (var i = 0; i < e.Information.Items.Count; i++)
    {
        Debug.WriteLine('Component Name=' +
                    e.Information.Items[i].Name +
                    "<BR/>");
        Debug.WriteLine('Failure Reason=' +
                    e.Information.Items[i].Reasons.ToString(16) +
                    "<BR/>");
        Debug.WriteLine('Renewal GUID=' +
                    e.Information.Items[i].RenewalId +
                    "<BR/>");
    }



    //  Invoke the revocation               
    var renewalStatus = await ComponentRenewal.RenewSystemComponentsAsync(e.Information);
    Debug.WriteLine("RenewSystemComponentsAsync: " +
                    renewalStatus.ToString() +
                    "<BR/>");

    e.Completion.Complete(false);
}
