 CreateFromSignedFile support is incomplete (and documented as such).
 It's main use is to get a certificate from a signed file (like an
 Authenticode signed EXE file). For your sample the use of
 CreateFromCertFile should be used (and should work).
 However the code shouldn't throw a NullReferenceException in this case.

+The certificate is in PEM (base64) format. This format isn't supported
+by the .NET framework, so it must be converted to DER before decoding.
+This is simple to do:
+a. remove both header and footer
+b. remove line endings
+c. get the binary using Convert.FromBase64String
+d. create a new X509Certificate with the buffer
+I'll keep this bug open because I'll fix the (most probably wrong)
+exception, NullReferenceException, in CreateFromSignedFile after
