I have quicky perused a shop copy of Robert Martins' C# book.
The key sections IMHO appear to be :

- pages 293-298
- chapter 26 and chapter 27

Of the seven Use Cases defined and then implemented by Robert Martin, what
have you implemented (as defined by the above) ??

If you have not implemented all of them, or have implemented things that
were *not defined* by Robert Martin, then you have not provided a *like
for like* implementation.

What does "approximate" mean ??
Either the code implements the payroll system in Robert Martins' book, or
it doesn't. Which is it ??

I have read all the code located at that URL again.

1. Allowing for my ignorance of C# (feel free to correct me) , I see is
what appears to be code for a *native (Windows) GUI* for a payroll
application, and *test harnesses* for the GUI.

I do not see any *domain/application logic* for a payroll application.


2. Written big and bold is the following :

<quote>

Agile Principles, Patterns, and Practices in C#: Chapter 38: The Payroll
User Interface: Model View Presenter

</quote>

Now, which chapters of Robert Martins' book for the payroll example does
this code relate to (note for the non-stupid : rhetorical question) ... ??
