Question

I was looking at sample code from MSDN just now and came accross:

namespace IListSourceCS
{
    public class Employee : BusinessObjectBase
    {
        private string      _id;
        private string      _name;
        private Decimal     parkingId;

        public Employee() : this(string.Empty, 0) {} // <<--- WHAT IS THIS???
        public Employee(string name) : this(name, 0) {}

Answer 1

It calls the other constructor in that class with that signature. Its a way of implementing the constructor in terms of other constructors. base can also be used to call the base class constructor. You have to have a constructor of the signature that matches this for it to work.
