Hi, The first thing you should check, is if you use a Release wt.dll with a debug build or vice versa, as that will not work. This is generally the case with MSVC code: you cannot mix debug and release builds.
If you build a Debug project -> link to wtd.lib If you build a Release project -> link to wt.lib Check this in the right-click->Properties->Linker settings of your hello world project.
