I'm using a scaffolding in visual studio 2017 now, but I want to set up my own scaffolding template and controller and I want to replace the previous one
Play around with all MVC templates at C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\ItemTemplates\CSharp\Web\MVC\1033
Refer: How do I create my own Scaffold Template in ASP.NET MVC 3?
