C# (.NET) Community Sums Up Annual Voting for Best Libraries of 2024

The annual voting among C# and .NET developers has concluded. This year, the community selected projects that truly changed the approach to building modern applications. We have compiled for you the complete list of winners in key categories — from web frameworks to tools for testing and data handling.

Categories and Winners

Best Web Framework: FastEndpoints — a lightweight alternative to classic MVC, offering high performance and a minimalistic API.
Database Library: EF Core 8 — the updated version of Entity Framework Core with support for JSON columns and improved migrations.
Testing Tool: Testcontainers — allows running integration tests with real containers without leaving the .NET environment.
Best Development Utility: FluentValidation — continues to dominate in model validation thanks to clean code and flexible rules.
Open Source Project of the Year: Polly — a library for managing resilience and retry policies, indispensable in microservice architecture.
HTTP Library: RestSharp — the new release 110.0 brought support for source generators and improved compatibility with AOT compilation.
UI Testing Tool: Playwright for .NET — a fast and cross-browser tool that surpassed Selenium in popularity within the community.
Best Serialization Library: System.Text.Json — remains the de facto standard thanks to native performance and integration with .NET 8.

Why These Libraries?

The voting showed that the C# community is increasingly focused on performance, security, and ease of use. The winners are not just popular utilities, but tools that solve real problems: reducing build times, simplifying testing, and improving application fault tolerance.

What's Next?

Developers recommend paying attention to newcomers: FusionCache (hybrid cache) and NetEscapades.AspNetCore.SecurityHeaders (header protection) received unexpectedly many votes, indicating a growing interest in security and caching. If you are working with .NET 8 or preparing for migration to .NET 9, include these libraries in your toolkit — they have already proven their effectiveness.

The full list of nominees and voting statistics can be found on the official website of the .NET Foundation community. And if you want to be the first to know about new tools — follow the updates on our portal.
