    a. you might do so purely out of argo cult, i.e. because someone told you this was the right thing to do™, and that's a silly exercise. b. you could also be doing this for a good reason: to use the interface with a mocking tool like NSubstitute

  • PeachPie

    PeachPie - the PHP compiler and runtime for .NET and .NET Core

    Project mention: .NET 8 – .NET Blog | news.ycombinator.com | 2023-11-14

    Project mention: Show HN: Actual Chat – Blending text and voice into a single medium | news.ycombinator.com | 2023-12-08

    - Even frequent exchanges like, “Hey, I’m heading to Costco, need anything?” where the follow-up is easier spoken than typed, or may require a brief brainstorming - “Oh, remember our neighbors are visiting us on Sunday?”

    That’s how 8 years later (2 years ago) me and my co-founder decided to implement a new chat app.

    — Technology —

    To make it short, I’ll post just one point here: Actual Chat is based on Fusion (https://github.com/servicetitan/Stl.Fusion) - think MobX / computed observables, but distributed. In Actual Chat, the state it manages spans from our servers to every client app, creating an eventually consistent “state mesh”. The unified state management, where clients and servers use exactly the same abstraction to “observe” the changes happening to any bit of content, is quite a challenge from the technology standpoint. IMO it alone deserves a brief look.

    P.S. Thank you for reading up to this point!

  • AvalonStudio

    Cross platform IDE and Shell

    Project mention: What happened to AvalonStudio? | /r/AvaloniaUI | 2023-05-06

  • mockhttp

    Testing layer for Microsoft's HttpClient library. Create canned responses using a fluent API.

    Project mention: Mock heavy tests | /r/dotnet | 2023-06-01

    I'd say that without wanting to refactor the code a little bit (maybe moving those HttpClients into a service so that they are easily mocked) your best bet would be to use something like WireMock or MockHttp.
