.NET Open Source Projects

.NET is a development platform for building and running applications across web, desktop, cloud, and other environments. Its runtime, language support, and shared libraries help developers create services and user-facing software, connect to databases and external systems, and handle tasks such as document generation and reporting. The platform supports multiple programming languages, with C# widely used for .NET development.

Open source .NET tools include libraries, frameworks, developer utilities, and integrations for common application needs. When choosing one, consider its license, release history, maintenance activity, supported .NET versions, dependencies, and fit with your existing stack. These tools can help individual developers, teams, and organizations extend applications, automate workflows, or evaluate implementation options while retaining access to the source code.
