Question: return value of CertOpenStore

[drauch]

According to the Microsoft Docs CertOpenStore returns NULL if it fails. Using CsWin32 the return type of CertOpenStore is "HCERTSTORE", which is a value type, which is never null.

How can I properly test for failure?

// Option 1:
if(returnValue == default)

// Option 2:
if(returnValue.Value == null)

Best regards,
