This works for .Net Core. Call on your Soap client:

client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication =

                {
                    CertificateValidationMode = X509CertificateValidationMode.None,
                    RevocationMode = X509RevocationMode.NoCheck
                };
