ASP.NET MVC. How is your frontend organized?

Question

ASP.NET

Good afternoon, colleagues.
Tell me, do you use the latest front-end trends in your projects? I mean Grunt(Gulp)/Bower/Less/Sass/Stylus/BEM?
It is very interesting to see how ASP.NET MVC projects look like with a heaped frontend.
If anyone knows public repositories with such projects, please share.
I would also be grateful for links to articles / videos / courses / books on the topic. But preferably a level higher than "now we will create a new project, connect Angular and make this element move."
