I am currently teaching myself c# but am confused by the following syntax:
new Deck( new Card[] {} )
where the Deck constructor looks like this:
public Deck(IEnumerable<Card> initialCards)
what does the {} bit mean?

It is an array initializer, and in this instance initializes an empty array.
It can also be used as follows:
int[] bling = new [] { 1, 2, 3 };
or
int[] bling = { 1, 2, 3 };

It is a collection initializer, can be used as follows
new Card[] {
new Card(),
new Card(),
new Card()
};
To initilise an array of cards of length 3 containing three card objects. As you have it, it will be an empty array.

I think the term is array initializer. Collection initializers work by calling
Add, which doesn't make sense for an array.It initialize an empty array.If you have a class like this :
class student {
private string name;
private int age;
}
you can initialize this :
student a = new student { name = "a", age = 10};
Sorry for my mistake above. You can initilize an array of student :
student[] students = new student[] {new student {name = "a", age = 10}, new student {name = "b", age = 20 }};

you still have a stray colon.
