StructureMap polymorphism!

We have circled back to using polymorphism to tackle the problem described here and here but instead of using Activator.CreateInstance we are now using StructureMap like so:

For<IWebServiceVersion>().Use<WebServiceVersion13>().Named("Web Service 13");

 
 

...and like so:

public IContainer Container { get; set; }
public IWebServiceVersion WebServiceVersion(int version)
{
   return Container.GetInstance<IWebServiceVersion>("Web Service " + int);
}
