    Reactive UI, it can feel strange at first but once you understand it you will never go back. Give it a try https://www.reactiveui.net/, https://github.com/reactiveui/ReactiveUI

  • GitHub repo Xamarin.Forms

    Xamarin.Forms Official Home

    Project mention: For a list of 20-60 equally sized row with the same layout, that's sandwiched between text and other controls, and where the number of rows won't change. Would you use a ListView with a DataTemplate or a CollectionView with a DataTemplate, and if one or the other, then why? | reddit.com/r/xamarindevelopers | 2021-06-13

    I think i will pick CollectionView because of the interesting ItemSizingStrategy property you can set it to MeasureAllItem which will make your CollectionView measure every item then display it while the user scrolls, or the other choice MeasureFirstItem which will measure the first item and apply it's size on all items in the CollectionView and that what you want i think. This made a noticeable difference in the performance when the user scrolls. But many developers reported issues that still exist currently in the CollectionView, you can check them out on the Xamarin Forms repo Please note that images loading may slow down the scrolling, if this was a problem for you then you can use gildex Nuget package to speed up images loading.

  • GitHub repo NLog

    NLog - Advanced and Structured Logging for Various .NET Platforms

    Project mention: Using NLog in a .NET 5 Console Application with Dependency Injection | dev.to | 2021-05-22

    It is recommended to read the NLog Tutorial. For more detailed information about config file can be found here.

  • GitHub repo Refit

    The automatic type-safe REST library for .NET Core, Xamarin and .NET. Heavily inspired by Square's Retrofit library, Refit turns your REST API into a live interface.

    Project mention: How to make Dapr client works well with Refit and RestEase | dev.to | 2021-03-08

    We can use Refit or RestEase to make it better to read and use just like above.

  • GitHub repo Uno Platform

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

    Project mention: GUI in C# while using Linux (.NET Core) | reddit.com/r/csharp | 2021-06-13

    There's also Uno which should support Linux as well.

  • GitHub repo xamarin-forms-samples

    Sample apps built using the Xamarin.Forms framework

    Project mention: .NET MAUI: .NET Multi-Platform App UI | news.ycombinator.com | 2021-04-20

    > Plus you can't share UI code between Android and iOS. You still need to build the UI's natively with no code reuse.

    Utterly false - Xamarin Forms is totally cross-platform UI; you're probably mistaking it for Xamarin Native, which is used as a target renderer for each platform. Look at this sample project: https://github.com/xamarin/xamarin-forms-samples/tree/master...

    The .iOS and .Android project folders target each platform respectively, with a single project shared between them that defines UI that is rendered onto each platform. You claim to have experience with using it, but obviously haven't done anything even as simple as a HelloWorld.

  • GitHub repo MVVMCross

    The .NET MVVM framework for cross-platform solutions, including Xamarin.iOS, Xamarin.Android, Windows and Mac.

  • GitHub repo MessagePack for C# (.NET, .NET Core, Unity, Xamarin)

    Extremely Fast MessagePack Serializer for C#(.NET, .NET Core, Unity, Xamarin). / msgpack.org[C#]

    Project mention: Json locations | reddit.com/r/gamedev | 2021-05-05

    The solution is always use a data contract serializer. Json.NET can of course be configured as such. My favorite serializer is MessagePack.

  • GitHub repo mobile

    The mobile app vault (iOS and Android). (by bitwarden)

    Project mention: Bitwarden no longer accepts master password | reddit.com/r/Bitwarden | 2021-06-09
  • GitHub repo Caliburn.Micro

    A small, yet powerful framework, designed for building applications across all XAML platforms. Its strong support for MV* patterns will enable you to build your solution quickly, without the need to sacrifice code quality or testability.

  • GitHub repo SkiaSharp

    SkiaSharp is a cross-platform 2D graphics API for .NET platforms based on Google's Skia Graphics Library. It provides a comprehensive 2D API that can be used across mobile, server and desktop models to render images.

    Project mention: Real World Map Generation; now with Roads, Water, (dummy) Buildings, Zombies and Overmap | reddit.com/r/cataclysmdda | 2021-05-02

    I didn't thought this well enough; I had the impression that I could use some sparse data structure or an array of a smaller-than-RGB-values type. But I really rely on image manipulation with the Skia library (via SkiaSharp) for some key processes. The improvements I could get from an array are not worth it the complexity of reinventing the wheel several times.

  • GitHub repo Akavache

    An asynchronous, persistent key-value store created for writing desktop and mobile applications, based on SQLite3. Akavache is great for both storing important data as well as cached local data that expires.

    Project mention: COM or C++/CLI layer for long-term maintenance? | reddit.com/r/cpp | 2021-05-30

    I would give CppSharp a crack first. It generates a .net wrapper using pinvoke.

  • GitHub repo xamarin-macios

    Bridges the worlds of .NET with the native APIs of macOS, iOS, tvOS, and watchOS.

    Project mention: Application.Main (System.String[] args) SIGABRT: Index was out of range. Must be non-negative and less than the size of the collection. | reddit.com/r/xamarindevelopers | 2021-04-09
  • GitHub repo Microcharts

    Create cross-platform (Xamarin, Windows, ...) simple charts.

    Project mention: Your experiences with Microcharts - The good, bad and ugly | reddit.com/r/xamarindevelopers | 2021-06-04

    Interested to hear who's using Microcharts and for those using it what have been your experiences? Do you feel this is as good as SyncFusion for charting, have you come across problems with using Microcharts, do you use it but you modified some charts, or maybe are you coding up your own charts with SkiaSharp?

  • GitHub repo Xamarin.Essentials

    Essential cross platform APIs for your mobile apps.

    Project mention: Can anyone clarify what this ‘Pegasus API’ is? Is this Norman on iPhone 11? | reddit.com/r/iosdev | 2021-05-21

    I don't know where you're seeing "xamarin/Essentials", but that's a repo for code used in writing cross-platform mobile applications. That message refers to this issue: https://github.com/xamarin/Essentials/pull/1457. It's something that was fixed in the project 7 months ago.
