    Project mention: Open-source cross-platform C# library that encode .BMP files? | reddit.com/r/csharp | 2023-03-14

    Found this issue that basically say it's not supported in skia directly, and it's right, from this page it seems only supported on iOS/Mac. This is pretty frustrating considering the documentation of SkiaSharp Encode() doesn't mention it.

    Currently I'm using LiteNetLib (https://github.com/RevenantX/LiteNetLib) and it's working pretty well. There is a little input lag but it's more than acceptable.

    Project mention: C# Complex Web Scraper: Looking for feedback / code review? | reddit.com/r/csharp | 2023-02-24

    MassTransit, SlimMessageBus, and SilverBack abstract interactions with message queueing systems. Some of what you are trying to do (I didn't read it deep enough to know exactly what you're using the queue for) would be done as a queue configuration instead (e.g. ordering, de-dupe, etc.).

    I use DDNS with Cloudflare, which offers free DNS. I built an open source Windows client for this (could be cross-platform, just haven't bothered yet).

    Project mention: For new projects, do you prefer EF, ADO, Dapper or something else? | reddit.com/r/dotnet | 2022-03-29

    We use https://github.com/nreco/data in our products, similar to Dapper but with built-in SQL generation for CRUD-queries (it is very easy to compose filters in run-time) + hand-written SQL may be concentrated in one place (app-level 'dataviews').
