    CppSharp

    CppSharp

    Tools and libraries to glue C/C++ APIs to high-level languages

    CppSharp is a tool and set of libraries that facilitates the usage of native C/C++ code with the .NET ecosystem. It consumes C/C++ header and library files and generates the necessary glue code to surface the native API as a managed API. Such an API can be used to consume an existing native library in your managed code or add managed scripting support to a native codebase. The supported target languages at present are C# and C++/CLI. It can also be used as a library to parse native code into a syntax tree with a rich declaration and type information model. Generates the glue binding code from a syntax tree of the native code. Provides APIs for parsing of C/C++ source code into a syntax tree. Mirrors the Clang's C/C++ AST and type system classes in C# APIs.

    ImageProcessor

    ImageProcessor

    Wrapper around System.Drawing for the processing of image files

    A .NET library for on-the-fly processing of images. ImageProcessor is a collection of lightweight libraries written in C# that allows you to manipulate images on-the-fly using .NET 4.5+. It consists of two main libraries ImageProcessor, for desktop and application use and ImageProcessor.Web, a dynamic image processing extension built for ASP.NET. It’s lighting fast, extensible, easy to use, comes bundled with some great features and is fully open source. ImageProcessor is free and open source but developing it has taken thousands of hours of my time and a large part of my sanity. If you feel like dropping me a few precious pounds (there’s no obligation) it would go a great way to ensure that I can afford to take the time to continue to improve the library. It's fast, extensible, easy to use, comes bundled with some great features and is fully open source.

    ML.NET

    ML.NET

    Open source and cross-platform machine learning framework for .NET

    With ML.NET, you can create custom ML models using C# or F# without having to leave the .NET ecosystem. ML.NET lets you re-use all the knowledge, skills, code, and libraries you already have as a .NET developer so that you can easily integrate machine learning into your web, mobile, desktop, games, and IoT apps. ML.NET offers Model Builder (a simple UI tool) and ML.NET CLI to make it super easy to build custom ML Models. These tools use Automated ML (AutoML), a cutting edge technology that automates the process of building best performing models for your Machine Learning scenario. All you have to do is load your data, and AutoML takes care of the rest of the model building process. ML.NET has been designed as an extensible platform so that you can consume other popular ML frameworks (TensorFlow, ONNX, Infer.NET, and more) and have access to even more machine learning scenarios, like image classification, object detection, and more.

    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).

    NLua

    NLua

    Bridge between Lua and the .NET

    Bridge between Lua world and the .NET (compatible with .NET/UWP/Mac/Linux/Android/iOS/tvOS). NLua is a fork project of LuaInterface (from Fábio Mascarenhas/Craig Presti). You can use/instantiate any .NET class without any previous registration or annotation. NLua runs on top of KeraLua binding, it encodes the string using the ASCII encoding by default. If you want to use UTF-8 encoding, just set the Lua.State.Encoding property to Encoding.UTF8. Calling instance methods: To call instance methods you need to use the : notation, you can call methods from objects passed to Lua or to objects created inside the Lua context. Calling static methods: You can call static methods using only the class name and the . notation from Lua. If you are using Xamarin.iOS you need to Preserve the class you want to use inside NLua, otherwise the Linker will remove the class from final binary if the class is not in use.

    A Lua implementation for the Dynamic Language Runtime (DLR)

    A Lua implementation for the Dynamic Language Runtime (DLR). NeoLua is an implementation of the Lua language. Currently, the implementation is on the level of Lua_5.3. The goal is to follow the reference of the C-Lua implementation and combine this with full .NET Framework support. That means it should be easy to call .NET functions from Lua and it should be easy to access variables and functions from a .net language (e.g. C#, VB.NET, ...).

    Vanara

    Vanara

    A set of .NET libraries for Windows implementing PInvoke calls

    This project contains various .NET assemblies that contain P/Invoke functions, interfaces, enums and structures from Windows libraries. Each assembly is associated with one or a few tightly related libraries. For example, Shlwapi.dll has all the exported functions from shlwapi.lib; Kernel32.dll has all for both kernel32.lib and kernelbase.lib. All assemblies are available via NuGet and provide builds against .NET 4.5, 4.8, 5.0, 6.0, .NET Standard 2.0, Core 3.1 and support SourceLink. Extensions are available for WinForms, WPF, and UWP projects. If you need support for other .NET versions, look to versions 3.3.15 and earlier. This project releases new versions every few weeks after sufficient testing. New releases are cataloged, along with release notes, in the Releases section and all NuGet packages are published to nuget.org. Each GitHub push triggers an AppVeyor build. The owners thank them for the free Open-Source account! The status of that build is in the header of this page.

    YamlDotNet

    YamlDotNet

    YamlDotNet is a .NET library for YAML

    YamlDotNet provides low-level parsing and emitting of YAML as well as a high-level object model similar to XmlDocument. A serialization library is also included that allows to read and write objects from and to YAML streams. YAML, which stands for "YAML Ain't Markup Language", is described as "a human-friendly data serialization standard for all programming languages". Like XML, it allows to represent of any kind of data in a portable, platform-independent format. Unlike XML, it is "human friendly", which means that it is easy for a human to read or produce a valid YAML document. The library has now been successfully used in multiple projects and is considered fairly stable. The library is compatible with mono's Ahead-of-Time compilation (AOT), and should work correctly on platforms that depend on it, such as Unity.

    passcore

    passcore

    A self-service password management tool for Active Directory

    PassCore is a very simple 1-page web application written in C#, using ASP.NET Core, Material UI (React Components), and Microsoft Directory Services (Default provider). It allows users to change their Active Directory/LDAP password on their own, provided the user is not disabled. PassCore does not require any configuration, as it obtains the principal context from the current domain. I wrote this because a number of people have requested several features that the original version did not have. The original version of this tool was downloaded around 8000 times in 2.5 years. My hope is that the new version continues to be just as popular. There really is no free alternative out there (that I know of) so hopefully, this saves someone else some time and money. We recommend use the docker image and redirect the traffic to nginx.
