The template contains a project and test case examples. When a new project is created from this template, it contains all NuGet references and a sample test case class.
Set “Start external application” in the Debugger options and point to your Gui.Winforms.YatsApplication.exe
It should be enough to copy this .zip file to <USER>\Documents\Visual Studio X\Templates\ProjectTemplates and restart VS, then select the template when creating a new project.
Happy hacking!
