You'll need the AirSim GitHub project locally, use AirLib/AirLib.vcxproj. Open MyLib.sln to open the solution. You will likely need to refresh each projects References, I used Project references. MyLib is a "Hello World" type C++ Library to simulate AirLib.lib. MyLibWrapper is a C++ DLL that wraps MyLib (and also AirLib.lib). MyLibConsole is a C# application that calls MyLibWrapper. Turboasin is a randomly chosen math method in AirLib.lib.
