Providing custom ServiceHost

I want to have some initialization code for my IIS-hosted service. I have read this article, it says (one of variants):

By deriving from ServiceHost type, you can implement the protected method ServiceHostBase.InitializeRuntime.

My question: Can I provide my own custom ServiceHost type to IIS?

Another way to do this is via file-less activation in the Web.config file. In your <system.serviceModel> section, add the following:

<serviceActivations>
  <add relativeAddress="Service.svc" 
       service="SomeNamespace.Service1" 
       factory="SomeNamespace.MyServiceHostFactory"/>
</serviceActivations>

This enables you to host a service in IIS without having a physical .svc file. This is a WCF 4.0+ feature, however.

As the article suggests, you can provide a ServiceHostFactory to IIS that initializes your service host.

First, define the factory in the .svc file:

<%@ServiceHost Language="C#" Factory="SomeNamespace.MyServiceHostFactory" %>

Then create the factory and host classes:

class MyServiceHostFactory : ServiceHostFactory
{
    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
    {
        return new MyServiceHost(serviceType, baseAddresses);
    }
}

class MyServiceHost : ServiceHost
{
    public MyServiceHost()
    {
        // initialize, add endpoints, behaviors, etc.
    }
}

You can also override InitializeRuntime if you like. In the article they use it to log the virtual directory in which the service is running.
