Assembly: System (in System.dll)
Protocols such as Secure Sockets Layer (SSL) and Secure MIME (S/MIME) allow the inclusion of additional certificates for use in validating a certificate chain; these certificates can prove to be useful in the validation process. This property allows these certificates to be passed to the chain validation engine. By default, this collection is empty.
