Hi
Ran into this issue this afternoon: Create new android app with the
following code
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
// Get our button from the layout resource,
// and attach an event to it
Button button = FindViewById<Button>(Resource.Id.MyButton);
button.Click += button_Click;
ServicePointManager.ServerCertificateValidationCallback +=
validatedCertificate;
}
void button_Click(object sender, EventArgs e)
{
HttpWebRequest req = new HttpWebRequest(new
Uri(@"https://wsklo2059.dragonslair.net:8090/IsAlive/";));
WebResponse res = req.GetResponse();
}
private bool validatedCertificate(object sender, X509Certificate
certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
return true;
}
But validatedCertificate is never called and pressing the button results in
a crash:

This is on m4a 4.4.55 - I suspect that somewhere in the depths of mono, my
validation callback is being undone as the behavior is the same as if I
don't do this validation.
The same code works in a Winforms app so it's down to M4A.
I suppose I should upgrade to the latest... will give that a go and report
back if it fixes things.
Regards
Stephan
