  <div>

  AsymmetricCipherKeyPair keyPair = createASymRandomCipher();
  RsaPrivateCrtKeyParameters KeyParams = (RsaPrivateCrtKeyParameters)keyPair.Private;
  RSAParameters rsaParameters = new RSAParameters();

  rsaParameters.Modulus = KeyParams.Modulus.ToByteArrayUnsigned();
  rsaParameters.P = KeyParams.P.ToByteArrayUnsigned();
  rsaParameters.Q = KeyParams.Q.ToByteArrayUnsigned();
  rsaParameters.DP = KeyParams.DP.ToByteArrayUnsigned();
  rsaParameters.DQ = KeyParams.DQ.ToByteArrayUnsigned();
  rsaParameters.InverseQ = KeyParams.QInv.ToByteArrayUnsigned();
  rsaParameters.D = KeyParams.Exponent.ToByteArrayUnsigned();
  rsaParameters.Exponent = KeyParams.PublicExponent.ToByteArrayUnsigned();

  RSACryptoServiceProvider rsaKey = new RSACryptoServiceProvider();
  
  rsaKey.ImportParameters(rsaParameters);

  
  X509Certificate2 cert = new X509Certificate2();

  cert.PrivateKey = rsaKey; -----    here it is giving a "m_safecertcontext is an invalid handle" an exception

  private static AsymmetricCipherKeyPair createASymRandomCipher()
  {
  RsaKeyPairGenerator r = new RsaKeyPairGenerator();
  r.Init(new KeyGenerationParameters(new SecureRandom(),1024));
  AsymmetricCipherKeyPair keys = r.GenerateKeyPair();
  return keys;
  }
