extension-methods

OK, I've probably misunderstood something here but, as far as I can see ...

An extension method has to be contained in a module, not a class
You can't make methods in modules Static/Shared
Therefore you can't use an extension method on a class without instantiating it.

In other words you can't make an extension method on String called "MyExtensionMethod" and use:

String.MyExtensionMethod("String")

But instead ..

Dim test As String
test.MyExtensionMethod("string")

Is this correct? Or is there a way I can get extension methods to work as static methods?
