Resource File in a class library in .Net

What type of resource? A string resource or something else? For string resources you might want to use property settings instead. For other resource types, try adding a new item to the project; it is possible to add a resource item. I am nor sure what to do from there; I managed to add a couple of HTML pages as resources to a project but I am not sure of how I did it. The .Net way of doing it is less clear than it is for C++ MFC and for Windows API applications.
