Now tell me, is that shallow or deep?

Public Sub New(ByVal array As Double(,))
    Me._matrix = array

Private _matrix as double(,)
Public Sub New(ByVal array As Double(,))
    Me._matrix = array.Clone

for copy/clone of value types or arrays of a value type, shallow == deep

Whereas with an array of reference types there would only be a subtle difference?

MSDN states[^]

A shallow copy of an Array copies only the elements of the Array, whether they are reference types or value types, but it does not copy the objects that the references refer to. The references in the new Array point to the same objects that the references in the original Array point to.

In the case of value-types, the result would be identical; you'd end up with an array of values.

I don't understand the identical bit. [..] Perhaps pedantry but in this case, at least for understanding, forgiveable pedantry I feel...

In the first case you have a pointer to an existing instance of an array in the second case you create a new instance of an array with the same structure as the one you cloned?

The point is if for some reason you wanted to let one user copy another user's favourites, what should you do? Just point to the same list?

in your sample though, you catch and throw the general purpose exception for no reason

I had read into it that what I am doing is saying that if anything I wasn't
expecting happens, just re-throw the same thing to ensure you don't lose it,
i.e. it's a side effect of a Try block. Maybe I assumed that without it I would
in effect be 'swallowing' all other exceptions, but maybe that only happens if I
catch the general purpose one and then leave the catch block empty?
