opencvsharp
OpenCV wrapper for .NET
OpenCV wrapper for .NET. Some Docker images are provided to use OpenCvSharp with AppEngine Flexible. The native binding (libOpenCvSharpExtern) is already built in the docker image and you don't need to worry about it. OpenCvSharp won't work on Unity and Xamarin platform. For Unity, please consider using OpenCV for Unity or some other solutions. OpenCvSharp does not support CUDA. If you want to use the CUDA features, you need to customize the native bindings yourself. Objects of classes, such as Mat and MatExpr, have unmanaged resources and need to be manually released by calling the Dispose() method. Worst of all, the +, -, *, and other operators create new objects each time, and these objects need to be disposed of, or there will be memory leaks. Despite the using syntax, the code still looks very verbose. -

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. -

Xamarin.iOS & Xamarin.Mac
Bridges the worlds of .NET with the native APIs of macOS, iOS, tvOS
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.
