Obtain the public key's hash from a X509Certificate2
I hold a X509Certificate2 object, I can access the public key via the PublicKey property. For a different API I need to obtain the public key's SHA-1 hash. Is there a simple way to get it from the PublicKey property?
I tried the following:
var sha1 = SHA1.Create().ComputeHash(signerCert.PublicKey.???)
But what to put instead of the "???". It doesn't look like there is some kind of "Raw" data property.

The answer seems to be signerCert.GetPublicKey() instead of accessing the PublicKey property directly.
