    AppTestStudio

    AppTestStudio

    Automate your apps, games, and Android emulators

    AppTestStudio (ATS) is an automated development environment, you can build, test, and automate Windows applications and android emulators. Quickly and interactively create automated actions by building Events either with pixel color matching, or using OpenCV image matching. Then attach actions to the events such as clicking or dragging. The multi processing (multiple scripts at the same time) was removed now only a single script can be run at one time. It was too confusing for some users which made the experience frustrating. If multiple concurrent scripts are needed just run an additional instance of ATS. The Package Name is used to launch the application when the emulator starts. If the Package Name is configured, pressing the "Start Emulator + Launch App" button will launch the instance of Nox player specified in the instance to launch (in 2. below). Package Name is recommended but not required, if you don't want or have the Package Name, Press the "Start Emulator".

    Refit

    Refit

    The automatic type-safe REST library for .NET Core, Xamarin and .NET.

    Refit is a library heavily inspired by Square’s Retrofit library, and it turns your REST API into a live interface. Refit currently supports the following platforms and any .NET Standard 2.0 target. Every method must have an HTTP attribute that provides the request method and relative URL. There are six built-in annotations: Get, Post, Put, Delete, Patch and Head. The relative URL of the resource is specified in the annotation. A request URL can be updated dynamically using replacement blocks and parameters on the method. A replacement block is an alphanumeric string surrounded by { and }. Parameters that are not specified as a URL substitution will automatically be used as query parameters. This is different than Retrofit, where all parameters must be explicitly specified. Round-tripping route parameter syntax: Forward slashes aren't encoded when using a double-asterisk (**) catch-all parameter syntax.

    SubsCheck-Win-GUI

    SubsCheck-Win-GUI

    A GUI program interface designed by SubsCheck for Windows users

    SubsCheck-Win-GUI is a Windows-based graphical application written in C# (for the .NET platform) designed to help Windows users check and manage subscription links (for proxy nodes) easily via a GUI rather than CLI scripts. The application provides a user interface for loading subscription links or node lists, performing checks (e.g., reachability, latency), and presenting results in a user-friendly view. It also supports auto-update of version information and links to downloads, as evidenced in its release notes (version 2.0.1.7 optimizing update mechanism). The tool caters to those who may prefer a desktop environment rather than deploying and debugging worker scripts themselves; it fills the niche of “subscription manager” on Windows. Because it deals with subscription feeds (for proxies), it also indirectly supports workflows similar to the WorkerVless2sub project but focused on the client/desktop side rather than backend generation.

    MockHttp for HttpClient

    MockHttp for HttpClient

    Testing layer for Microsoft's HttpClient library

    MockHttp is a testing layer for Microsoft's HttpClient library. It allows stubbed responses to be configured for matched HTTP requests and can be used to test your application's service layer. MockHttp defines a replacement HttpMessageHandler, the engine that drives HttpClient, that provides a fluent configuration API and provides a canned response. The caller (eg. your application's service layer) remains unaware of its presence. MockHttpMessageHandler defines both When and Expect, which can be used to define responses. They both expose the same fluent API, but each works in a slightly different way. Using When specifies a "Backend Definition". Backend Definitions can be matched against multiple times and in any order, but they won't match if there are any outstanding Request Expectations present (unless BackendDefinitionBehavior.Always is specified).

    Bridges the worlds of .NET with the native APIs of macOS, iOS, tvOS, and watchOS. This module is the main repository for both Xamarin.iOS and Xamarin.Mac. These SDKs allow us to create native iOS, tvOS, watchOS and macOS applications using the same UI controls we would in Objective-C and Xcode, except with the flexibility and elegance of a modern language (C#), the power of the .NET Base Class Library (BCL), and two first-class IDEs—Visual Studio for Mac and Visual Studio—at our fingertips. This repository is where we do development for the Xamarin.iOS and Xamarin.Mac SDKs. The preferred method for installing Xamarin.iOS and Mac is to use the Visual Studio installers (Windows, Mac). The team also strongly recommends using the latest Xamarin SDK and Xcode whenever possible.

    ServiceStack

    ServiceStack

    Simple, fast, versatile and full-featured services framework

    One framework to power them all. Write your HTTP APIs once and take advantage of end-to-end typed integrations for all popular web, mobile and desktop platforms. ServiceStack's primary goal is to enhance the value of System APIs which serve as the blueprint that most features centered around. By using simple & pure dependency-free DTO models decoupled from any implementation we're free to continue layering on features which now sees ServiceStack APIs as the most versatile in the world where the same high-performance APIs can be consumed from HTTP in any combination of Route, QueryString, FormData or a myriad of data formats, via popular resilient MQ Servers whilst simultaneously supporting legacy integrations like SOAP or adopting new technologies like gRPC without sacrificing any native HTTP integrations. To maximize the value of APIs we're focused beyond the API boundary by making it as simple as possible for API Consumers to call your APIs.

    SkiaSharp is a cross-platform 2D graphics API for .NET platforms

    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. Building SkiaSharp is mostly straight forward. The main issue is the multiple dependencies for each platform. However, these are easy to install as they are found on the various websites. If you are just working on managed code, it is even easier as there mays to skip all the native builds. Because there are multiple distros of Linux, and we cannot possibly support them all, we have a separate NuGet package that will contain the supported binaries for a few distros.

Issues and tasks for all but the API reference repository are tracked here. We have a large community using these resources. We make our best effort to respond to issues in a timely fashion. .NET is a free, open-source development platform for building many types of applications. Share functionality between different applications and application types using class libraries. With .NET, your project code and files look the same, regardless of the type of application you build. With each application you have access to the same language, API, and runtime capabilities. .NET allows you to use platform-specific functionality, such as operating system APIs. Some examples are Windows Forms and WPF on Windows and the native bindings to each mobile platform from Xamarin.
