Top 5 C# Web Framework Projects

Web Frameworks

  1. ASP.NET Core

    ASP.NET Core is a cross-platform .NET framework for building modern cloud-based web applications on Windows, Mac, or Linux.

    Project mention: How to Use Libuv In Your Zig Project | dev.to | 2025-05-10

    Libuv describes itself as a multi-platform support library with a focus on asynchronous I/O. It is widely used in many web servers (e.g., Kestrel) and runtimes such as Node.js and Python (via uvloop). As of Zig 0.14.0, there is no native async I/O, so you must work directly with threads or create your own async API using OS primitives like epoll or kqueue. In many cases, you would likely choose a cross-platform library rather than implementing your own async API. That’s where using libuv, libevent, or libxev (written in Zig) becomes useful.
