This is the best way (ref: https://stackoverflow.com/a/256278/372666)

public static class Foo
{
    private static readonly Destructor Finalise = new Destructor();

    static Foo()
    {
        // One time only constructor.
    }

    private sealed class Destructor
    {
        ~Destructor()
        {
            // One time only destructor.
        }
    }
}
