An error with the certificate occurs. For example:

This constructor creates a new X509Certificate object using a handle for the Microsoft Cryptographic API certificate context, PCCERT_CONTEXT.
Important
|
|---|
|
This constructor creates a copy of the certificate context. Do not assume that the context structure you passed to the constructor is valid; it may have been released. You can get a copy of the current PCCERT_CONTEXT structure from the Handle property, but it is valid only during the lifetime of the X509Certificate object. |
