I have received an sdk for the avaya ip office telephony platform, and I need to start developing an interface for the very basic functions. All the documentation relates to c or c++ . They do mntion however that Devlink.dll, (which is what applications need to link to) can be used in any language that supports dynamic link libraries. I believe that c# supports dll's, therefore that means I can access the functionality via this dll even though I'm developing in C#? All I would need to do link to it? How is this normally achived in C#. This application will eventually be a .net application by the way.
