Issue from @keystroke.

When a new X509Certificate2 object is created with the empty constructor, it succeeds. However, it is initialised with its Handle property set to IntPtr.Zero. So accessing certain properties on that object try to dereference that Handle and cause an access violation.

Steps to reproduce

$cert = [System.Security.Cryptography.X509Certificates.X509Certificate2]::new(); $cert.SendAsTrustedIssue

Expected behavior

Value is possibly $null or False.

Actual behavior

PowerShell crashes (the window disappears)

Further Information

Also try

[System.Security.Cryptography.X509Certificates.X509Certificate2]::new() | fl *

This crash reproduces back to Windows PowerShell 5.1.

The property accessed in the particular repro is a script property that triggers this method:

It seems that X509Certificate2 has a property called Handle which is set to IntPtr.Zero by default, causing the access violation.
