But may be this question needs higher understanding. My scenario is I want to use dotnetnuke CMS with visual studio 2013/2015. But I don't know how and from where I start. I want to make a website using CMS and manage Admin Panel.
Please help.
You don't need to use Visual Studio at all to build a website using DNN.
You'll need to install DNN7. Here is a good place to start: https://www.youtube.com/watch?v=BBatw8mgPrg
Then, you can build out the website using the DNN CMS.
You may find that you want to install additional modules or a theme for your website. Ask more questions or use Google when you get to that point.
