Частичное доверие в WPF 4

Question

Я начал новый проект в WPF 4 (.NET 4) и пытаюсь выяснить, могу ли я запустить его в режиме xbap. Мне нужно запустить приложение в режиме полного доверия с новым режимом, доступным в .NET 4, который спрашивает конечного пользователя, следует ли запускать приложение с полным доверием.

Я установил " Безопасность " режим «Полное доверие» приложение, и оно просто отлично строит. Когда я запускаю его, выдается исключение, и в сообщении об ошибке IE отображается следующая ошибка.

Есть ли способы обойти это ??

Единственный способ запустить самоподписанное приложение xbap с полным доверием - это добавить сертификат на компьютер клиента (что может быть невозможно в большинстве случаев) или добавить URL сайта в список доверенных. места. Я нашел последнее наиболее удобным, и приложение запускается так, как будто оно подписано действительным сертификатом, выданным доверенным органом.

Обратите внимание, что это возможно только в .NET 4.0 и не будет работать в предыдущих версиях WPF / .NET
