Could we get a release with NetStandard 2.0 support?

Thanks for this library... I like this implementation so far the best of all of the others available for C#.

In experimenting with this library I am unsure of how to get the framework to keep the state of a collection inside a class as it is currently not working. I have the following fake Person class.

[MementoClass] public class Person { public string Name { get; set; } public List<string> Addresses { get; set; } public DateTime DateOfBirth { get; set; } }

When I run the following code, it will not restore the addresses that existed before I cleared them. What must I do to make that happen?

`var person = new Person { Addresses = new List { "12180 N Lazy River", "4311 W Summit Ranch" }, DateOfBirth = DateTime.Now, Name = "David D" };
var personList = new List { person };
var memento = Memento.Create().RegisterProperty(person, p=>p.Name).RegisterProperty(person, p=>p.Addresses).RegisterCollection(personList);

        try
        {
            person.Name = "Changed";
            person.Addresses.Clear();
            throw new Exception();
        }
        catch (Exception x)
        {
            memento.Rollback();
        }

        var addressCount = person.Addresses.Count; //Equals 0 when should equal 2 if restored correctly.`

Hi, I've recently discovered this memento pattern implementation via a container and it features exactly what I wanted to achieve in my app. The only problem I have is as far as I've seen it needs the class to be adorned with, at least, a MementoClassAttribute, but I'm actually working with 3rd party classes from a closed library, so I can't modify them.

Mocking with the source code I saw I only have to implement my own IPropertyAnalyzer (wich, in this case is almost equals as the standard one, only getting all the properties even without the class adorner). I saw the code is actually structured in a way to allow dependency injection but all the required interfaces are internal to the assembly, so I couldn't come with a way to extend it without modifying the source.

Is there any way to achieve my goal without adorning the class or modifying the source code? If there isn't one, would you accept contributions or forks in that direction?
