Static classes work in the same way as classes apart from one fundamental difference. They cannot be initalised.

Essentially, you are not able to use the new operator on a static class.

We have this static CategoryHelper class.

public static class CategoryHelper
	public static List<int> GetAllCategoryIds()
		return new List<int>();

If we wanted to call the GetAllCategoryIds method, how would we do it?
