本文介绍如何在.NET Framework 3.0中通过扩展System.ServiceModel.Activation.ServiceHostFactory并提供自定义服务主机工厂来解决WCFCF多绑定问题。自定义服务主机工厂能够选择合适的基地址，从而在IIS中支持每个站点的多个绑定。

Supporting Multiple IIS Bindings Per Site

Ref: http://blogs.msdn.com/rampo/archive/2007/06/15/supporting-multiple-iis-bindings-per-site.aspx

If you see this error when you are hosting in IIS then most probably you have multiple IIS bindings per scheme in your web site. WCF in .Net Framework 3.0 ,out of the box, does not support multiple binding per site, but this can enabled by extending the System.ServiceModel.Activation.ServiceHostFactory, and providing a CustomServiceHostFactory. CustomServiceHostFactory picks the appropriate base address for the application. The Factory attribute in the ServiceHost directive is set to the CustomSerivceHostFactory.

The only drawback is every developer hosting their application will need to change the svc file to provide the CustomServiceHostFactory, which picks the appropriate base address.

Sample Code

public class MultipleIISBindingSupportServiceHostFactory : ServiceHostFactory

{

protected override ServiceHost CreateServiceHost( Type serviceType, Uri [] baseAddresses)

{

Uri [] requiredAddress = GetAppropriateBase(baseAddresses);

return base .CreateServiceHost(serviceType, requiredAddress);

}

Uri [] GetAppropriateBase( Uri [] baseAddresses)

{

List < Uri > retAddress = new List < Uri >();

foreach ( Uri address in baseAddresses)

{

if (address.DnsSafeHost == "localhost" )

{

retAddress.Add(address);

}

return retAddress.ToArray();

}

In the svc file, fill in the Factory attribute

<%@ServiceHost Factory="NS.MultipleIISBindingSupportServiceHostFactory" Service="CalculatorService" %>
