Cannot set Web Service constructor parameter

问题:

Question Back ground:

I have a project consisting of a DLL, a web service and a test project. Currently I'm simply trying to set the web service constructor string parameter through the use of Unity.

The issue & error:

The following shows the constructor structure of the web service class 'VersionControlFacade':

 private string _url;

 public VersionControlService()
 {
 }

 public VersionControlService(string url)
 {
    _url = url;
 }

If I simply pass the 'url' parameter as shown in the following code it is fine:

 var newVersionControlFacade = new VersionControlFacade(@"http://somelink.com");

When I try and pass it using my Unity IoC container as shown:

 var container = new UnityContainer();
 container.RegisterType<IVersionControlFacade, ProxyHandler>();
 container.RegisterType<Proxy>();
 container.RegisterType<VersionControlService>(new InjectionConstructor(@"http://somelink.com"));
 return container.Resolve<IVersionControlFacade>();

The following error is being throw stating that the web service does not contain a constructor that takes a string parameter even though it clearly does.:

Result Message:

Test method Test_Unity threw exception: System.InvalidOperationException: The type VersionControl.WebService.VersionControlService does not have a constructor that takes the parameters (String).

Can anyone steer me in the right direction here? Do I need to re-add the web reference for it to see this new constructor?
