Automapping error: The type does not have a default constructor

this will help Bogard, you rock! The most recent version of Automapper now supports projection conversions:
http://lostechies.com/jimmybogard/2014/12/23/automapper-3-3-feature-projection-conversions/
code :
Mapper.CreateMap<CameraDisplayMapPto, CameraDisplayMap>()
      ---->   .ConstructProjectionUsing(x => new CameraDisplayMap(x.Camera, x.Display));

I hope this helps . the problem is, that automapping tries to automap your repository, that it shouldn't map, only entities. your RecipeConfiguration should tell FNH which classes to map.
code :
public bool ShouldMap(Type type)
{
    return type.In(typeof(Category), typeof(Foo));
}
public bool ShouldMap(Type type)
{
    return type.Namespace == "MyNamespace.Mappings"
}
AutoMap.AssemblyOf<Category>(t => t.Namespace == "MyNamespace.Mappings"))

This might help you Because the constructor method is how you initialize an object created with a class in javascript - this will always be an empty object if you are trying to access it within the function parameters of the constructor itself.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes#Class_body_and_method_definitions
code :
class Foo {
    constructor(foo = () => console.log(this), bar = () => console.log('baz')) {
      foo(); // {}
      bar(); // baz
    }
}

const foo = new Foo();

this one helps. Since ScannerConfiguration requires a parameter, why don't you initialize it yourself?
code :
var sc = new ScannerConfiguration("some string value");
_onDisk = Mapper.Map( _inMemory, sc );

Does that help To correctly implement the singleton pattern, you must avoid making your constructor public. Therefore, you should avoid Java.Lang.Object which seems to force you to have a public constructor.

Hope this helps Your constructor is called stacks while the class is called Stack - in C++ the constructors has to have the same name as the class, i.e. Stack.
