//Starting using the SetBuilder<T> class:
var person = new SetBuilder<Person>()
    .WithProperty(p => p.Name, s => "Edu")      //Can handle with any type
    .WithProperty(p => p.Married, m => true)
    .WithProperty(p => p.BirthDate, b => new DateTime(2005, 9, 22))
    .WithProperty(p => p.Partner, p =>
    {
        return new SetBuilder<Person>()
            .WithProperty(p => p.Name, n => "Livia")      
            .WithProperty(p => p.Married, m => true)
            .WithProperty(p => p.Gender, Gender.Female)     //Can pass a value directly  
            .Build();
    })
