5. Test load cert with different flags:

(If not specify X509KeyStorageFlags or use X509KeyStorageFlags.DefaultKeySet, it will be same behavior as X509KeyStorageFlags.MachineKeySet)
5.1 DefaultKeySet
var bytes = File.ReadAllBytes(@"D:\Temp\temp_certs\test_selfsignedcert\testselfsignedcert.pfx");
var cert = new X509Certificate2(bytes, "password", X509KeyStorageFlags.DefaultKeySet);
Console.WriteLine("Thumbprint: {0}", cert.Thumbprint);
Console.WriteLine("Subject: {0}", cert.Subject);
Console.WriteLine("HasPrivateKey: {0}", cert.HasPrivateKey);
