The GitHub Extension for Visual Studio enhances the development workflow by enabling users to manage pull requests directly within Visual Studio, eliminating the need to switch between windows. This extension introduces a new pull request window that allows users to review code, make modifications, and push updates back to GitHub. It also supports collaboration on forked branches for upstream repository contributors. Users can install the extension from the Visual Studio gallery or download it from the official website. Initially released as an open-source project under the MIT license, the extension encourages community involvement through issue logging and contributions, spearheaded by Sara Ford.
