ABP
Open-source web application framework for ASP.NET Core! Offers an opinionated architecture to build enterprise software solutions with best practices on top of the .NET. Provides the fundamental infrastructure, cross-cutting-concern implementations, startup templates, application modules, UI themes, tooling and documentation.
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: PeachPie Compiler: Compile and run PHP on top of .NET runtime | news.ycombinator.com | 2024-10-08
we have attempted to use it for that, but it was really hard and we ended up rewriting from scratch.
The activity graph on GitHub says it is mostly dead. There is some activity, but at best it is in maintenance mode. It used to be sponsored, but not anymore IIRC
