Hi, i am in quest for the same and have had partial success with it. Technically saying you a class library of all drivers and controls is made and compiled , it should create dll which could be used with any .net language c++ / c# / vb. Unfortunately i tried it in VS c# express 2010 and did not work out.
I have realized that VS express 2012 allows to create multi language project so you can open the solution of advanced hmi vb project , add a c# project to it , add reference to vb projects in you c# project , also add reference to two dll kept in support folderS , build.
This should add controls to your form.
Problem with this approach - i am getting the driver controls in my toolbox but graphic controls ie tank , pipe , valves etc are not showing up yet its good enough for you i think ..
