WCF Services on shared hosting (This collection already contains an address with scheme http.)

问题

When trying to call a WCF service I receive the following error:

This collection already contains an address with scheme http.  There can be at most one address per scheme in this collection. 
Parameter name: item

The Goog tells me that the solution is as follows (when using .net 3.5, which I am):

  <baseAddressPrefixFilters> 
    <add prefix="http://mydomain.com.au"/> 
  </baseAddressPrefixFilters> 

However, when I try to add this to the section of my web.config it tells me it is invalid.

回答1:

You should use this instead in 3.5:

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>

if you move to 4.0 you can use svc less activation as shown here: ServiceRoute + WebServiceHostFactory kills WSDL generation? How to create extensionless WCF service with ?wsdl
