    FlaUI

    FlaUI

    UI automation library for .Net

    FlaUI is a .NET library which helps with automated UI testing of Windows applications (Win32, WinForms, WPF, Store Apps,...). It is based on native UI Automation libraries from Microsoft and therefore kind of a wrapper around them. FlaUI wraps almost everything from the UI Automation libraries but also provides the native objects in case someone has a special need that is not covered (yet) by FlaUI. Some ideas are copied from the UIAComWrapper project or TestStack.White but rewritten from scratch to have a clean codebase. To use FlaUI, you need to reference the appropriate assemblies. So you should decide, if you want to use UIA2 or UIA3 and install the appropriate library from NuGet. You can of course always download the source and compile it yourself. The entry point is usually an application or the desktop so you get an automation element (like a the main window of the application). On this, you can then search sub-elements and interact with them.

    LINQ to DB

    LINQ to DB

    Linq to database provider

    LINQ to DB is the fastest LINQ database access library offering a simple, light, fast, and type-safe layer between your POCO objects and your database. Architecturally it is one step above micro-ORMs like Dapper, Massive, or PetaPoco, in that you work with LINQ expressions, not with magic strings, while maintaining a thin abstraction layer between your code and the database. Your queries are checked by the C# compiler and allow for easy refactoring. However, it's not as heavy as LINQ to SQL or Entity Framework. There is no change-tracking, so you have to manage that yourself, but on the positive side you get more control and faster access to your data. In other words LINQ to DB is type-safe SQL. Alternatively, you can implement custom settings provider with ILinqToDBSettings interface. You can generate POCO classes from your database using T4 templates.

    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.

    MarkovJunior

    MarkovJunior

    Probabilistic language based on pattern matching

    The MarkovJunior project is a procedural generation engine that uses rule-based systems inspired by Markov processes to create complex structures and patterns. It allows users to define transformation rules that iteratively modify a grid or space, producing outputs such as textures, maps, and architectural layouts. The system is highly flexible, supporting both deterministic and probabilistic rule application to generate diverse results. It is particularly popular in game development and generative art, where procedural content can enhance variability and creativity. The project provides tools for defining rules, visualizing outputs, and experimenting with different configurations. Its design emphasizes simplicity while still enabling complex emergent behavior. Overall, MarkovJunior is a powerful framework for procedural generation using rule-based approaches.

    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.

    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.

    Vlc.DotNet

    Vlc.DotNet

    .NET control that hosts the audio/video capabilities of the VLC libs

    Vlc.DotNet is a .net library that hosts the audio/video capabilities of the VLC libraries. In other words, it's a .net wrapper around libvlc. That's why a new control has been written. To be fair, first versions of Vlc.DotNet were built with that technique, but back then, there were issues in the .net framework causing the memory usage to explode. As of 2018, this issue is resolved. The old WPF control was just a wrapper around the WinForms control. This led to some issues (Airspace issue...) and lacked some WPF-ish features. Vlc.DotNet is a .net library that hosts the audio/video capabilities of the VLC libraries. In other words, it's a .net wrapper around libvlc. It can work on any .net framework version starting from .net 2.0 and .net standard 1.3 (starting from Vlc.DotNet 2.2.1). On the front-end side, two components are currently available to make it easy to integrate in your apps. One is for WinForms, the other for WPF.

For the build process of the compiler we create our own "specialized" version of the CSharp Compiler. The source for this compiler and codeanalysis.dll is in the Tools folder. This compiler will translate some of the Roslyn Namespaces from CSharp into XSharp to prevent name conflicts when assemblies of both origins are in memory at the same time. Make sure you have VS 2019 or 2017 installed. The preferred edition is Enterprise. Make sure you have Java JDK on your machine and that you have the Java binaries folder in your Path. If you do not have Vs 2019 Enterprise you can set 2 environment variables to the VS version and edition you have installed.
