I am trying to create 2 wcf services that use the same
IOperationBehavior. Which ever service is created first works fine,
but the 2nd one created bombs out with this error:
The value could not be added to the collection, as the collection
already contains an item of the same type: 'MyOperationBehavior'. This
collection only supports one instance of each type.
Parameter name: item
Here is a little stack trace info:
System.Collections.Generic.KeyedByTypeCollection`1.InsertItem(Int32
index, TItem item) +16301212
Castle.Facilities.WcfIntegration.WcfExplicitExtension.Install(ServiceEndpoint
endpoint, Boolean withContract, IKernel kernel, IWcfBurden burden)
+308
Castle.Facilities.WcfIntegration.ServiceHostExtensions.Castle.Facilities.WcfIntegration.IWcfExtensionVisitor.VisitEndpointExtension(IWcfEndpointExtension
extension) +217
Castle.Facilities.WcfIntegration.ServiceHostExtensions.Install(ICollection`1
extensions, IWcfBurden burden) +110
Castle.Facilities.WcfIntegration.AbstractServiceHostBuilder.ConfigureServiceHost(ServiceHost
serviceHost, IWcfServiceModel serviceModel, ComponentModel model) +833
Castle.Facilities.WcfIntegration.AbstractServiceHostBuilder`1.Build(ComponentModel
model, M serviceModel, Uri[] baseAddresses) +77
Castle.Facilities.WcfIntegration.WcfServiceExtension.CreateServiceHost(IKernel
Kernel, IWcfServiceModel serviceModel, ComponentModel model, Uri[]
baseAddresses) +548
Castle.Facilities.WcfIntegration.WindsorServiceHostFactory`1.CreateServiceHost(String
constructorString, Uri[] baseAddresses) +183

Here is how I have registered the behavior and services
Component.For<ValidateOperationBehavior>().Attribute("scope").Eq(WcfExtensionScope.Explicit),
Component.For<IAccountRegistrationService>().ImplementedBy<AccountRegistrationService>().ActAs(new
DefaultServiceModel().Hosted().AddExtensions(typeof(ValidateOperationBehavior))),
Component.For<IRetailService>().ImplementedBy<RetailService>().ActAs(new
DefaultServiceModel().Hosted().AddExtensions(typeof(ValidateOperationBehavior)))
Should this behavior work? Is there some other way I should be
registering this behavior?
Thanks for any help or pointers?
