Sitefinity 4.0 Beta: Deploying projects to ISPs

  • Sitefinity 4.0 Beta: Deploying projects to ISPs
  • I deployed a SF 4.0 Beta project to my isp.

    1) Deployed the db. Worked fine.
    2) Depoyed the web site files
    3) Edited the data config file and changed the connection string.

    Now, i can hit the SF site fine. Its just one page:

    But if i hit the SF admin area, i run into a problem. The dashboard comes up fine, but clicking the Pages option returns this error:
    Message from webpage: This collection already contains an address with schemd http.&nbsp: There can be at most one address per scheme in this collection. <br>parameter name: item

    This occurs each time i click the Pages tab. Other tabs seem to work fine.

  • Hey Ken,

    I'm having the same problem but I think I found a workaround.  This error is stemming from running WCF services from a site with multiple bindings in IIS (multiple host headers per site).  This IIS configuration is very common and I guess this is the intended design of WCF services my Microsoft.

    My workaround is:

    using System;
    using System.Collections.Generic;
    using System.Web;
    using System.ServiceModel;
    using System.Configuration;
    namespace MySite.Web.Services
        public class WcfHostFactory : Telerik.Sitefinity.Web.Services.WcfHostFactory
            public WcfHostFactory()
                : base()
            protected override ServiceHost CreateServiceHost(Type type, Uri[] uri)
                string baseServiceHost = ConfigurationManager.AppSettings["baseServiceHost"];
                IDictionary<string, int> schemes = new Dictionary<string, int>();
                List<Uri> clean = new List<Uri>();
                for (int i = 0; i < uri.Length; i++)
                        if (uri[i].Host == baseServiceHost)
                            schemes.Add(uri[i].Scheme, i);
                    catch (ArgumentException)
                return base.CreateServiceHost(type, clean.ToArray());

    There's probably a more graceful way to do it but this was my first pass at it.

    Then I replace the Telerik WcfHostFactory with my wrapper in the PagesService.svc file:

    <%@ ServiceHost Language="C#" Debug="true" Service="Telerik.Sitefinity.Modules.Pages.Web.Services.PagesService" Factory="MySite.Web.Services.WcfHostFactory" %>

    Add an appSettings key to your web.config:

    <add key="baseServiceHost" value=""/>

    And it should work.  Of course, you will have to find and replace all instances of Telerik.Sitefinity.Web.Services.WcfHostFactory in your .svc files.  that's my next step.

  • Hi Bryan,

    Thank you for providing the workaround. We are going to resolve this issue by providing the ability to set default bindings for services.

  • Did you try setting the baseAddressPrefixFilters element in your web.config?

        <serviceHostingEnvironment aspNetCompatibilityEnabled="true">
                <add prefix="" />

    Here is Microsoft's documentation regarding multiple IIS bindings,

    Edit: It looks like this solution currently doesn't work and has been logged in the teams bug list. See forum thread.
