I created class library and after compiling it, I want to access or use it in other projects. I successfully attached the class dll in my project but why is it that everytime I want to use the method properties I need to create new instance of the class?

MyClassMethod myClsMethod = new MyClassMethod();
int var1 = myClsMethod.GetTotalTax();

I've seen VFPToolkit source code but using it is very easy. There is no need to create new instance of the class. Why?

TIA
