Top 23 C# Library Projects

  • FASTER

    Fast persistent recoverable log and key-value store + cache, in C# and C++.

    • Project mention: A MySQL compatible database engine written in pure Go | news.ycombinator.com | 2024-04-09

    You would be surprised by performance of modern .NET :)

    Writing no-alloc is oftentimes done by reducing complexity and not doing "stupid" tricks that actually work against JIT and CoreLib features.

    For databases specifically, .NET is actually positioned very well with its low-level features (intrisics incl. SIMD, FFI, struct generics though not entirely low-level) and high-throughput GC.

    Interesting example of this applied in practice is Garnet[0]/FASTER[1]. Keep in mind that its codebase still consist of un-idiomatic C# and you can do way better by further simplification, but it already does the job well enough.

  • Depressurizer

    A Steam library categorizing tool.

    • Project mention: I wrote an app for myself to filter my library by HLTB | /r/SteamDeck | 2023-12-11

    Another thing you can do is use a Steam tag management system like Depressurizer to automatically tag games with their approximate HLTB time (eg. 1-5 hours could be a category, 6-10 hours could be another category), then on Steam Deck you can use the Tab Master plugin for Decky to show each HLTB categories as a separate tab. There are probably other ways to display the categories as well.
