Visual Studio 2017 Installer Projects
The one thing that frustrates me a bit (other than iTunes) is how often the Visual Studio installer projects change from version to version. In fact, as of this writing there is no project template for Visual Studio 2017. It just so happened that the project that I was working on, was originally developed in Visual Studio 2015. It included a setup project that was now no longer available in Visual Studio 2017. It simply displayed the setup project as (incompatible).
