X509 guide/tutorial in C#

Question

Can anyone point me to a good introductory materials on X509 certificates with examples in C#.

Answer 1

I found this particularly helpful:

Nine simple steps to enable X.509 certificates on WCF

Also, if anyone's having trouble installing the windows devlopment sdk (to get MakeCert.exe), untick the c++ options in the installer and it seems to work fine.
