How to declare the Unity InjectionFactory in XML c

问题:

I'm in the process of moving our Unity configuration to the web.config file. I'm stuck on how to migrate the following code config to the xml format:

var container = new UnityContainer();
container.RegisterType<IPrincipal>(new InjectionFactory(x=> HttpContext.Current.User));
return container;

Here are the XML declartion:

<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
    <alias alias="IRepository" type="Model.IRepository, Model" />        
    <alias alias="Repository" type="Data.Repository, Data" />
    <container>
      <register type="IRepository" mapTo="Repository" />      
    </container>    
</unity>

InjectionFactory is the one thing that can't be represented in XML out of the box. In order for it to completely work, you'd have to write a C# parser that could work on the XML file, which was way more than I wanted to bite off at the time.

However, I do have a sample on bitbucket which shows a way to get a limited version of factory creation working via XML. Might give you some ideas.
