Restarting the service after opening the provider breaks the connection and forces you to restart the entire application.

Step by step:

  1. Open the provider NCryptOpenStorageProvider(myProvider, MS_KEY_STORAGE_PROVIDER, 0) — will be "00000000" (ERROR_SUCCESS)
  2. Restart the CNG Key Isolation service
  3. Reopen the provider NCryptOpenStorageProvider(myProvider, MS_KEY_STORAGE_PROVIDER, 0) — will be "80070006" (ERROR_INVALID_HANDLE)

How to properly reopen the provider after restarting the service without restarting the application?
