In celebration of Microsoft's release of Visual Studio 2015, the GitHub Extension for Visual Studio, which facilitates working on GitHub repositories within Visual Studio 2015, has been made open source under the MIT License. The project acknowledges the significant support from Microsoft and the contribution of various open source tools, libraries, and projects that facilitated its development. By making the extension open source, the team aims to give back to the community and encourage other developers to create their own Visual Studio extensions. Users can download the extension to experience its capabilities and are invited to contribute by filing issues or submitting pull requests to the project's repository.
