Add-on functions to a software application are made through a single dynamic linked library ('DLL'). After discovering, authenticating, and loading the DLL, the application may inspect the DLL to determine if it contains a function of a predetermined type. If the type is discovered, an object of the type may be instantiated and called. The inspection may evaluate metadata within the DLL to determine the precise characteristics of the function and compare the function to a predetermined type. Based on the authentication as well as the internal inspection of the DLL, extensions to existing software applications may be easily distributed and readily installed in an atomic fashion.
