Open Source C# Runtimes for Windows

.NET is a free, cross-platform, open source developer platform for building many different types of applications. With .NET, you can use multiple languages, editors, and libraries to build for web, mobile, desktop, games, and IoT. You can write .NET apps in C#, F#, or Visual Basic. C# is a simple, modern, object-oriented, and type-safe programming language. F# is a cross-platform, open-source, functional programming language for .NET. It also includes object-oriented and imperative programming. Visual Basic is an approachable language with a simple syntax for building type-safe, object-oriented apps. Whether you're working in C#, F#, or Visual Basic, your code will run natively on any compatible OS. Different .NET implementations handle the heavy lifting for you.

CoreCLR is the runtime for .NET Core, an open source, general purpose development platform maintained by Microsoft and the .NET community. It is a cross-platform runtime for cloud, IoT, and desktop apps and includes a just-in-time compiler called RyuJIT.

PeachPie is a modern PHP compiler based on the Microsoft Roslyn compiler platform and drawing from our popular Phalanger project. It allows PHP to be executed within the .NET framework, thereby opening the door for PHP developers into the world of .NET – and vice versa. Build, debug, profile, and diagnose your code in the family of .NET tools, including Visual Studio and VS Code. Seamlessly port your legacy PHP code to the modern, cross-platform, lightning-fast .NET Core. Leverage the best of both worlds and build .NET apps in C# and PHP. You can find an up-to-date status of the project in our Roadmap section. Please note that the status is dynamic; PeachPie is a work in progress, which means that the list of finished and planned features frequently changes and will be updated on a regular basis.

The .Net Runtime Library for Delphi (CNClrLibrary) is the best library to work with .Net framework and .Net libraries from Delphi. It is designed to provide a way to interact with applications written in anyone of the .Net languages (such as C#, Visual Basic.Net, Delphi.Net, JScript.Net, etc) from Delphi. CNClrLibrary allows Delphi to use .Net libraries without the need for registry entries, COM registrations, or changes to the .NET libraries. Competitive Advantages: - No extra dll is required when deployed. - No COM registration of .Net Libraries is required when deployed. - There are tools to generate your .Net Libraries into Delphi pas files. - Allows Delphi to consume .Net libraries as if they were native code. - Full access to .Net Framework Class Library. - Easy to use. CNClrLibrary can do so much: - Access .Net Framework Class Library. - Access Third Party .Net Libraries. - Access Your .Net Libraries. - etc Latest Version: 6.0.7.0

This project is a subproject of the WFMATH library, a library providing several complex mathematical primitives. This library will allow .NET programmers to use WFMATH in their code.

The dotNet4Java is a .Net Runtime Library for Java which helps Java developers work with .Net framework and 3rd party libraries in Java with ease. It is designed to provide a way to interact with applications written in anyone of the .Net languages (such as C#, Visual Basic.Net, Delphi.Net, JScript.Net etc) from Java. Competitive Advantages: - dotNet4Java JAR can be easily added to artefacts repository like maven or ivy. - dotNet4Java is single jar file that can be very easily added to any type of Java project EJB, applet, desktop, console or service. - No extra dll is required when deployed. - Full access to .Net Framework Class Library. - Lightweight and easy to use. - There are tools to import and generate .Net Libraries into Java class files. dotNet4Java can do so much: - Access .Net Framework Class Library. - Access Third Party .Net Libraries. - Access Your .Net Libraries. - Can invoke members of a .Net types. - etc Latest Version: 1.0.1.0
