Hello team,
Currently we are developing kmdf driver for windowsIOT core device, In order to establish connection between Application and Genericusbfn.sys, we are following following windows service code, "Install, start, stop, delete of a windows service works fine", but we observed one thing , we didn't get any prints which are in ServiceMain() function which means control is not entering into ServiceMain() function and we are getting following error StartServiceCtrlDispatcher -> failed.here i include screen shots and code we follow, could anybody please guid us how to solve.
NOTE: For developing windows service can i use console application template, if it is not relevant template could anybody tell us which template is used to develop windows service in c++.
