I wanted to find a framework that already had all the Boiler code needed for a business application: menus, sections, graphs, users, etc. While searching for such a framework, we noticed the .Net frameworks https://aspnetboilerplate.com and https://abp.io, which already have a lot of things "out of the box". As far as I understand, both frameworks are being developed either by related teams, or even by one team. And the teams are from Turkey. The ASP.NET Boilerplate framework has legacy code from older versions of the .Net Framework. The newer ABP framework does not have legacy, it is on .Net Core. Both frameworks have a decent number of stars on github.
