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.

Project mention: Malleable software: Restoring user agency in a world of locked-down apps | news.ycombinator.com | 2025-06-10
https://serenity.is/
I am 50 years old with a few decades of experience.
For past four years I have been voluntarily paying for Serenity's commercial offering (called StartSharp) in order to support them, as well as to express my gratitude for saving my sanity.
I mean, technically I could do with their free and open source version, as it packs plenty enough of punch.
C# / typescript / asp.net core / Visual Studio / linux deployment friendly, also under docker / works well enough with Postgres
