我创建了一个VPN配置文件，但未设置以下设置：名称，密码和身份验证方法。我试图以管理员身份运行项目，但它也没有起作用。有什么问题吗？

  auto mgr = ref new VpnmanagementAgent();

  auto  profile                          =   ref new VpnNativeProfile();
  profile->AlwaysOn                      =   true;
  profile->NativeProtocolType            =   VpnNativeProtocolType::L2tp;
  profile->Userauthenticationmethod      =   VpnAuthenticationmethod::PresharedKey;
  profile->ProfileName                   =   "TestVpn";
  profile->RememberCredentials           =   true;
  profile->RequireVpnClientAppUI         =   true;
  profile->RoutingPolicyType             =   VpnRoutingPolicyType::ForceAllTrafficOverVpn;
  profile->Servers->Append("101.99.74.214");  

  auto profileStatus    = mgr->UpdateProfileFromObjectAsync(profile);

  auto credentials      = ref new PasswordCredential();
  credentials->username = "vpn";
  credentials->Password = "vpn";  

  auto connectStatus  = mgr->ConnectProfileWithPasswordCredentialAsync(profile,credentials);
