CSLA .NET
A home for your business logic in any .NET application
CSLA .NET is a software development framework that helps you build a reusable, maintainable object-oriented business layer for your app. Created by Rockford Lhotka, this framework reduces the cost of building and maintaining applications. The framework enables developers to leverage the power of object-oriented design as the basis for creating powerful applications. Business objects based on CSLA automatically gain many advanced features that simplify the creation of Windows, web, service, and mobile interfaces. CSLA .NET allows great flexibility in object persistence, so business objects can use virtually any data sources available. The framework supports 1-, 2- and n-tier models through the concept of mobile objects. This provides the flexibility to optimize performance, scalability, security and fault tolerance with no changes to code in the UI or business objects. -

Microsoft Authentication Library .NET
Microsoft Authentication Library (MSAL) for .NET
MSAL.NET (Microsoft.Identity.Client) is an authentication library that enables you to acquire tokens from Azure AD, to access protected Web APIs (Microsoft APIs or applications registered with Azure Active Directory). MSAL.NET is available on several .NET platforms (Desktop, Universal Windows Platform, Xamarin Android, Xamarin iOS, Windows 8.1, and .NET Core). The MSAL library for .NET is part of the Microsoft identity platform for developers (formerly named Azure AD) v2.0. It enables you to acquire security tokens to call protected APIs. It uses industry-standard OAuth2 and OpenID Connect. The library also supports Azure AD B2C. Acquiring a token interactively enables the application to acquire a token after authenticating the user through an interactive sign-in. There are specificities, though depending on the platforms (Xamarin Android, Xamarin iOS, or UWP) -

Free and open-source robotic process automation (rpa)
taskt (formerly sharpRPA) is the first truly free, easy-to-use, and open-source process automation client built on the .NET Framework in C#. taskt allows you to build and design process automation without needing to write application code. taskt allows you to automate the boring stuff and create efficienies by giving you the power to craft a digital workforce that executes and performs rule-based automation. No API? No Problem! Included is a "what you see is what you get" bot designer with dozens of automation commands. An element recorder and screen recorder is also included that can record and replay scripted automation. taskt works by allowing a bot developer to design a bot configuration known as a script. The bot configuration is then intepreted by a script engine at run-time and executes against the bot developer's selected parameter inputs. Each command contains the definitions for the required inputs as well as the required logic at run-time. -

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. -

SharpShell
Create Windows Shell Extensions using the .NET Framework
SharpShell is a .NET library that allows developers to create Windows Shell extensions in managed code, simplifying what is traditionally a complex and low-level development process. It enables the creation of context menu handlers, icon overlays, and other shell integrations using C# instead of native C++. The library abstracts many of the complexities of COM programming, making it more accessible to developers who are familiar with .NET. It includes templates and examples that help developers quickly get started with building shell extensions. SharpShell also provides tools for debugging and testing extensions, improving the development experience. It is widely used for creating custom integrations within the Windows Explorer environment. Overall, SharpShell simplifies the process of extending Windows functionality through managed code. -

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. -

OpenIddict
Versatile OpenID Connect stack for ASP.NET Core and Microsoft.Owin
OpenIddict aims at providing a versatile solution to implement OpenID Connect client, server and token validation support in any ASP.NET Core 2.1 (and higher) application. ASP.NET 4.6.1 (and higher) applications are also fully supported thanks to a native Microsoft.Owin 4.2 integration. Developers looking for a simple and turnkey solution are strongly encouraged to use OrchardCore and its OpenID module, which is based on OpenIddict, comes with sensible defaults and offers a built-in management GUI to easily register OpenID client applications. Unlike many other identity providers, OpenIddict is not a turnkey solution but a framework that requires writing custom code to be operational (typically, at least an authorization controller), making it a poor candidate for the certification program. While a reference implementation could be submitted as-is, this wouldn't guarantee that implementations deployed by OpenIddict users would be standard-compliant. -

Orleans
Orleans is a cross-platform framework for building distributed apps
Orleans builds on the developer productivity of .NET and brings it to the world of distributed applications, such as cloud services. Orleans scales from a single on-premises server to globally distributed, highly-available applications in the cloud. Orleans takes familiar concepts like objects, interfaces, async/await, and try/catch and extends them to multi-server environments. As such, it helps developers experienced with single-server applications transition to building resilient, scalable cloud services and other distributed applications. For this reason, Orleans has often been referred to as "Distributed .NET". It was created by Microsoft Research and introduced the Virtual Actor Model as a novel approach to building a new generation of distributed systems for the Cloud era. The core contribution of Orleans is its programming model which tames the complexity inherent to highly-parallel distributed systems without restricting capabilities or imposing onerous constraints. -

SkiaSharp
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. -

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. -
