WCF RIA Services 4004 error

Question

Все работает отлично в IIS Express, но когда я отлаживаю локальный IIS, у меня возникла ошибка при попытке использования WCF в приложении (см. Ниже), который отображается в браузере, но VS нет.

[Window Title] 
Visual Studio Just-In-Time Debugger 

[Main Instruction] 
An unhandled exception ('Unhandled Error in Silverlight Application

') occurred in iexplore.exe [856]. 

The Just-In-Time debugger was launched without necessary security permissions. To debug this process, the Just-In-Time debugger must be run as an Administrator. Would you like to debug this process?

У меня есть решение. Моя голова, это работает так странно ...

Итак, вам нужно перейти на Панель управления - Программы и функции - Включить или выключить функции, и там вы должны включить ВСЕ Дерево служб WCF (также проверьте ASP.NET , если вы не проверите его раньше).
