Support for value types with default constructors about autofixture HOT 4 CLOSED

Possibly related: The ability to set the value of individual properties on an immutable type where all setters are private.

//This will result in a compile error because of inaccessible setter
//If the "newValue" was injected through the constructor this would work
var x = fixture.Build<MyImmutableClass>()
  .With(v => v.MyReadonlyPropery = "newValue")
  .CreateAnonymous();

I am trying to implement this one. Implementing checking for custom structs without constructors went well. However I have issues with allowing for that unsupported operation.

Initial code can be found here:
WojcikMike@ebda500

Short description goes as follows:
To Fixture I've added something like this:
new FilteringSpecimenBuilder(
new StructureWithoutConstructorSpecimenBuilder(), //throws exception with detailed message
new AndRequestSpecification(
new StructureSpecification(), //checks if it is custom struct
new NoConstructorSpecification())) //checks if it doesn't have constructors

I've created two classes:
SupportStructureDefaultConstructorsCustomization, SupportStructureDefaultConstructorsGenerator. and this is where the tricky parts are.

Generator creates structure itself so it is fine however I would have to pass it to fill all properties. To do this ideally my generator would have to land somewhere before Postprocessor with AutoPropertiesTarget. Any advices how to proceed?

The Auto-Properties feature is implemented by composing Postprocessor with an AutoPropertiesCommand, so your customization would need to do something like this:

fixture.Customizations.Add(
    new Postprocessor(
        new SupportStructureDefaultConstructorsGenerator(),
        new AutoPropertiesCommand());

You may need to use the Postprocessor constructor overload, that also takes as a third parameter an IRequestSpecification...
