Я продолжаю получать ошибку «Последовательность не содержит элементов» при попытке установить мои службы wcf.
вот код в моем global.asax:
_container = new WindsorContainer();
_container.Register(Component.For<IWindsorContainer>().Instance(_container))
.AddFacility<WcfFacility>()
.Install(Configuration.FromAppConfig())
.Install(FromAssembly.InDirectory(new AssemblyFilter(HttpRuntime.BinDirectory, "Web*.dll")));
вот мой раздел system.servicemodel в web.config:
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<client>
<endpoint address="http://commandservice.website.com/WebsiteCommandService.svc" binding="basicHttpBinding" contract="CommandService.IWebsiteCommandService" name="commandServiceClient"></endpoint>
</client>
</system.serviceModel>
А вот конфиг моего замка (внутри web.config):
<castle>
<components>
<component
id="commandService"
type="CommandService.WebsiteCommandService, CommandService"
wcfEndpointConfiguration="commandServiceClient" />
</components>
</castle>
Я упускаю что-то очевидное?

проблема, похоже, сейчас где-то в другом месте - похоже, что он пытается разрешить компонент, как если бы это был обычный объект, а не служба wcf. имея в виду, что служба работает - при попытке решить ее с помощью wcf я получаю сообщение об ошибке на ctor:
public WebSiteCommandService(ICommandService service)
{
_service = service;
}
Пишет, что нет компонента для ICommandService
почему клиентский контейнер пытается решить эту проблему?
это похоже на то, что вещи wcffacility полностью пропускаются?
