Uses for static generic classes?

Question

What are the key uses of a Static Generic Class in C#? When should they be used? What examples best illustrate their usage?

e.g.

Answer 1

The first blog post you mention shows a valid use (as a static repository class for an ActiveRecord implementation):

public static class Repository
{
    public static T[] FindAll { }

    public static T GetById(int id){ }

    public static void Save(T item) { }
}

Or if you wanted to implement different sort methods for Generic arrays:

public static class ArraySort
{
    public static T[] BubbleSort(T[] source) { }

    public static T[] QuickSort(T[] source) { }
}
