How to Programmatically Define a Single Endpoint for a WCF Service


I'm trying to allow for user configuration of a WCF service, including the IP and port number that the service listens on. The user has a separate config application that allows for these values to be set, but the problem I am running into is that the app.config MUST have an endpoint defined in order to create a new ServiceHost entry...but my endpoint is being defined in a separate configuration file and must then be bound programatically at runtime.

If I do the following (based on How to programatically modify WCF app.config endpoint address setting?:

        m_SvcHost = new ServiceHost(this);

        if (Config.ServiceEndpoint != null && Config.ServiceEndpoint != String.Empty)
                new BasicHttpBinding(),


the service will listen on BOTH the URI defined in the app.config, AND the URI defined in the configuration file. There is no way that I can find to remove the original endpoint or to create the service without an endpoint defined.

Writing to the app.config from the configuration application is not an option - I need to pull the configured value programatically from the separate XML config file....

any thoughts?

EDIT: the service runs as a Windows Service and exposes an HTTP endpoint, it is not running as a web service hosted in IIS - if that changes things at all


Does this help you? This code will allow you to respond to any address that you list in the CreateServiceHost() method.

public class CRSyncServiceHost : ServiceHost
    public CRSyncServiceHost(Type serviceType, params Uri[] baseAddresses) : base(serviceType, baseAddresses) { }

    protected override void ApplyConfiguration()

public class CRSyncServiceFactory : ServiceHostFactory
    protected override System.ServiceModel.ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        Uri newServiceAddress = new Uri("");
        CRSyncServiceHost newHost = new CRSyncServiceHost(serviceType, newServiceAddress);
        return newHost;

<%@ ServiceHost Language="C#" Debug="true" Service="CRSyncService" Factory="CRSyncServiceFactory" CodeBehind="CRSyncService.svc.cs" %>
