Unity InjectionConstructor for multiparam constructor overriding only single one

Question

I have a class with constructor like this:

public class Bar
{
    public Bar(IFoo foo, IFoo2 foo2, IFoo3 foo3, IFooN fooN, String text)
    {

    }
}

Unity can't do this out of the box. The best you can do is:

container.RegisterType(
    new InjectionConstructor(
        typeof(IFoo), typeof(IFoo2), typeof(IFoo3), typeof(IFooN), "123"));

Or you can use the SmartConstructor provided by the TecX project. This blog post describes some background.

Registration would look like this:

container.RegisterType(new SmartConstructor("text", "123"));
