Спасибо за публикацию оставшейся части кода.Я вижу, вы запускаете процесс повышенным.Я добавил это в свой тестовый сервис, и он все еще работает правильно.
Но я думаю, что проблема может быть в этой строке в GetLinkedTokeIfRequiered()
:
Marshal.Release(LINKED_TOKEN_INFO);
Это, очевидно, должно быть:
Marshal.FreeHGlobal(LINKED_TOKEN_INFO);
Исправьте это, и это может просто сработать.Как это ни странно, я поражен, что он не падает.
Мне нелегко копаться в этом.Взаимодействие с C # не моя сильная сторона.
Для удобства ОП, полный исходный код моей службы тестирования, написанный на C ++, который работает:
