How to modify WCF service configuration if services hosted on IIS?

Question

I have WCF service (NET 4) hosted on IIS. It configured via web.config. I just want to make some little changes at existsing configuration in runtime. It seems using custom ServiceHostFactory/ServiceHost force me to duplicate all settings in code. Is there any trick?

If you modify the configuration file during runtime, you will restart the application. In this case, you have two options - either do the configuration in code, or store the configuration information in a separate file, but then you'll have to read a separate file and may have to create the code to do that. Easier to do it in the code for this scenario, IMO :) — Tim, Oct 23 '15 at 18:00

Yes you can have a ServiceHostfatory :

<%@ ServiceHost Language="C#" Debug="true"   
                Service="IISHost.HelloService"   
                CodeBehind="/App_code/HelloService.svc.cs" 
                Factory="MyServiceHostFactory" %>

and you can have a ServiceHostFactory that instanciates you service. Because you instanciate your service "as usual" you can have some code that reads the XML configuration -look at code in the comments below :

public class MyServiceHostFactory : ServiceHostFactory{
 protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses ) {
    ServiceHost host = new ServiceHost(typeof(HelloService ));
    // add/modify the endpoints, Behaviors, ... through  
    // host.Description.Endpoints, host.Description.Behaviors …
    return host;
 }
}

Thanks a lot! Exactly what I need! – garry Oct 26 '15 at 10:04 — garry, Oct 26 '15 at 10:04
