Ok here are my simplified classes
public class Class1
{
couple of props and methods
public Class2 Class2
{
get
{
return _Class2;
}
set
{
_Class2 = value;
}
}
public class Class2
{
private Class3 Class3;
public Class3
{
get
{
return _Class3
}
set
{
_Class3 = value;
}
}
and Class3 with some props and methods.
Do I really need to declare any prop ? Test was just an example of
any property that i have in the classes.

You also don't show any property named Test on your classes. If class1
has a property named Test which is declared as "public class2 Test",
then your result map for class1 needs to select a class2 object
instead of a class3 object.
