How to serialize a custom class with YamlDotNet

I'm trying to serialize a custom class with YamlDotNet library.
Here is my class:

public class Person
{
    string firstName;
    string lastName;

    public Person(string first, string last)
    {
        firstName = first;
        lastName = last;
    }
}

And here is how I tried to serialize it:

StreamWriter streamWriter = new StreamWriter("Test.txt");
Person person = new Person("toto", "titi");
Serializer serializer = new Serializer();
serializer.Serialize(streamWriter, person);

But in my output file, I only have this : { }

What did I forget to do to serialize my class?

The default behavior of YamlDotNet is to serialize public properties and to ignore fields. The easiest fix is to replace the public fields with automatic properties:

public class Person
{
    public string FirstName { get; private set; }
    public string LastName { get; private set; }

    public Person(string first, string last)
    {
        FirstName = first;
        LastName = last;
    }
}

You could alter the behavior of YamlDotNet to serialize private fields relatively easily, but I do not recommend that.
