Required properties in .NET with a default constructor

One of my classes require that a default constructor be used for serialization purposes. However, since some of the properties are required, what is the best way to approach this such that I can require that properties be set.

From where I am standing, I see two possible scenarios:

I would keep it simple and don't mess with attributes.

public interface IDataValidator
{
    void ValidateData();
}

public string Serialize<T>(T obj):where T:IDataValidator
{
    obj.ValidateData();
    return Serialize(obj);
}

public T Deserialize<T>(string serializedObj):where T:IDataValidator
{
    T obj = Deserialize(serializedObj);
    obj.ValidateData();
}

public class Book : IDataValidator
{
    public string Isbn {get;set;}

    public Book(){}
    public Book(string isbn)
    {
        Isbn = isbn;
    }

    public void ValidateData()
    {
        if(string.IsNullOrEmptyOrWhiteSpace(Isbn)
            throw new ApplicationException("...");
    }
}
