Hey Crew,
After I Installed Microsoft Visual C++ Redistributable for Visual Studio 2017 from https://visualstudio.microsoft.com/downloads/ or Direct Link: https://go.microsoft.com/fwlink/?LinkId=746572. The tutorial worked as expected. Should that be added to the tutorial?

Can I get the dependency with a PackageReference?
