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 WebServiceHost, consider also implementing a factory that derives from the WebServiceHostFactory class.

The following example shows how to derive a class from WebServiceHostFactory.

To have your derived Web service host factory used, specify it in a .SVC file. The following example shows the syntax used in a .svc file.

<%@ServiceHost language=c# Service="Microsoft.Samples.MyWCFService" Factory="Microsoft.Samples.MyWebServiceHostFactory" %>
