Próbuję postępować zgodnie z przykładem Hello ServiceStack. Używam programu Visual Studio 2010, programu Windows 7 w wersji 64-bitowej, ale usługi IIS są skonfigurowane do uruchamiania aplikacji 32-bitowych. Utworzony przeze mnie projekt Hello wykorzystuje ASP.Net MVC3. Otrzymuję ten błąd podczas próby uzyskania dostępu do metadanych:Błąd ServiceStack Ładowanie WebHost Endpoint

Jak zainstalowałeś ServiceStack przez NuGet? Spróbuj zaktualizować zarówno ServiceStack, jak i WebActivator – mythz
Tak, przez Nuget. – cksanjose
Właśnie wypróbowałem najnowszą wersję NuGet, działa dla mnie. Czy to działa, gdy używasz wewnętrznego WebDevServer? (tzn. w Project Properties/Web/Use VS Dev WebServer) – mythz
