ServiceHostFactory Class

Factory that provides instances of ServiceHost in managed hosting environments where the host instance is created dynamically in response to incoming messages.

Namespace:  System.ServiceModel.Activation
Assembly:  System.ServiceModel.Activation (in System.ServiceModel.Activation.dll)

public class ServiceHostFactory : ServiceHostFactoryBase

The ServiceHostFactory type exposes the following members.

Public methodServiceHostFactoryInitializes a new instance of the ServiceHostFactory class.

Public methodCreateServiceHost(String, Uri[])Creates a ServiceHost with specific base addresses and initializes it with specified data. (Overrides ServiceHostFactoryBase.CreateServiceHost(String, Uri[]).)
Protected methodCreateServiceHost(Type, Uri[])Creates a ServiceHost for a specified type of service with a specific base address.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The managed hosting environments that support dynamic activation are Internet Information Services (IIS) and Windows Process Activation Service (WAS).

If you have implemented a custom derivative of ServiceHost, consider also implementing a factory that derives from the ServiceHostFactory class.

If you have implemented a custom derivative of ServiceHostBase instead, then consider also implementing a factory that derives your factory from ServiceHostFactoryBase directly.

This examples show how to use the ServiceHostFactory class:

	public class DerivedFactory : ServiceHostFactory 

		protected override ServiceHost CreateServiceHost( Type t, Uri[] baseAddresses ) 
			return new DerivedHost( t, baseAddresses ); 

		//Then in the CreateServiceHost method, we can do all of the
		//things that we can do in a self-hosted case:
		public override ServiceHostBase CreateServiceHost
				(string service, Uri[] baseAddresses)


			// The service parameter is ignored here because we know our service.
			ServiceHost serviceHost = new ServiceHost(typeof(HelloService),
			return serviceHost;
