    Project mention: .NET 6 Preview 1 Released | reddit.com/r/programming | 2021-02-17

    Yeah, I wonder how this announcement plays into that. There's been a wiki page regarding limitations for a long time, and I wouldn't be surprised if the realization was that an entirely different approach to EnC was in order.

  • GitHub repo Avalonia

    A cross platform XAML framework for .NET

    Project mention: .NET 6 Preview 1 Released | reddit.com/r/csharp | 2021-02-18

    One framework for creating powerful cross-platform games.

    Project mention: Need Help With Imported Assets | reddit.com/r/Unity3D | 2021-02-23

    The project you linked isn't compatible with Unity in any way. It looks like this is designed on top of MonoGame, a completely different game engine.

  • GitHub repo Bitwarden

    The core infrastructure backend (API, database, Docker, etc). (by bitwarden)

    Project mention: news.ycombinator.com | 2021-02-22

    What do you think about this reply on that thread? https://github.com/bitwarden/server/issues/589#issuecomment-...

  • GitHub repo csharplang

    The official repo for the design of the C# programming language

    Project mention: .NET 6 Preview 1 Released | reddit.com/r/fsharp | 2021-02-17

    They are working on them, but there aren't any news yet. Don't know if this feature is going to make it into C# 10, but I think it's discussed here.

    I'm wondering if anyone has any experience with asp.net boilerplate or abp.io what your thoughts are.

  • GitHub repo Gui.cs

    Console-based user interface toolkit for .NET applications.

    Project mention: Best python GUI to learn? | reddit.com/r/learnpython | 2021-02-23

    If your goal is is to make something cross-platform from a single code base; I recommend: Terminal.Gui. Every desktop has a terminal, and it has the added benefit of performing well over SSH and the like. The problem is people will think your app is old and busted because it's fast and looks like it's from the 80's.

  • GitHub repo Uno Platform

    Build Mobile, Desktop and WebAssembly apps with C# and XAML. Today. Open source and professionally supported.

    Project mention: Goodbye Electron, Welcome Flutter | reddit.com/r/programming | 2021-02-21

    Can anyone compare Flutter with https://platform.uno/ ? I thought .NET ecosystem would be richer.

    Seems interesting with the Docker exploit I guess. I would still recommend linpeas: https://github.com/carlospolop/privilege-escalation-awesome-...

    Most of these tricks are listed here at GTFOBins: https://gtfobins.github.io/ which is based on LOLBAS for Windows: https://lolbas-project.github.io/#

  • GitHub repo EntityComponentSystemSamples

    Project mention: Cross-platform deterministic physics with Unity DOTS physics and soft floats | reddit.com/r/Unity3D | 2021-02-15

    Somehow I cant find the Unity DOTS physics on Github to see what the license is. I found, for example, their DOTS Samples repository, which has a "Unity Companion License", meaning its " royalty-free copyright license to reproduce, prepare derivative works " etc. I would imagine all their github projects are like that. I could even ask on the forums if you would be willing to share the code in case the licence is ok (which I am sure it is judging by Unity's other repos)
