Making A General Functions Class Library That Will Be Used In Several Applications And Asp Pages?

making a general functions class library that will be used in several applications and asp pages, sometimes running at the same time.I've looked at a lot of samples on the web and they all show you to create an instance of the classlibrary namespace or the classlibrary class.

IE.
dim obj2 as new mycompany.mynamespace.myclass
dim n2 as integer
n2 = obj2.somefunction(...)

What I did was create my class library and put a class in it and declared a function as sharred, then created my dll.I don't have to create an instance of it and I can use it like the net framework by just coding

n2 = mycompany.mynamespace.myclass.somefunction(...).

The net framework does this, I mean once I imports it I don't have to make an instance of it in every function.All the samples I've seen about class libraries do not use the shared keyword.
