Load X509 certificate from disk .Net Core

Question

I've created an X509 certificate using OpenSSL. I am trying to load it using the Import method on the X509Certificate2 class, in .NET Core 2.0.

var cert = new X509Certificate2();
cert.Import(_path);

But get thrown the following exception:

System.PlatformNotSupportedException : X509Certificate is immutable on this 
platform. Use the equivalent constructor instead.

Which constructor should I be using / what is the correct way to load this certificate from disk?

Solution

You can use

var x509 = new X509Certificate2(File.ReadAllBytes(_path));

Have you tried new X509Certificate2(certificateAsByteArray), looking into the code of .net core import not implemented : github.com/dotnet/corefx/blob/…

@user1034912 sorry to hear that. What runtime version do you use? Do you have the private key included in the PFX or is it ephemeral?
