  • fsharp-hedgehog

    Release with confidence, state-of-the-art property testing for .NET.

    Project mention: Resources to learn the F# ecosystem | reddit.com/r/fsharp | 2022-10-15

    Unit testing: I personally use FsUnit, specifically FsUnit.Xunit. There's some other libraries like Expecto and Hedgehog (property testing), but I haven't found a reason to use them. I recently started experimenting a little with Hedgehog. FsUnit integrates well into Visual Studio, since it sits nicely on top of NUnit and xUnit, and it's done everything I've needed so far.

  • csharp-language-server

    Roslyn-based LSP language server for C#

    Project mention: Understanding the .NET ecosystem: The evolution of .NET into .NET 7 | news.ycombinator.com | 2023-03-21

    Sadly, OmniSharp (the LSP for vscode and nvim) isn't all that great. The performance is incredibly bad, easily orders of magnitude worse than VS and Rider.

    There is this alternative LSP, which I plan to try out still: https://github.com/razzmatazz/csharp-language-server
