• Visual Studio 2022 version 17.14.9 does not exist. The latest version as of my knowledge cutoff is 17.8.x. Please verify this version number is correct, as it may be a future version that doesn't exist yet.

Requires Visual Studio 2022 version 17.14.9 or later.

Ok
This pull request updates the Visual Studio installation instructions for setting up the GitHub MCP server in Copilot. The guide now reflects a more accurate minimum version requirement, clarifies the configuration steps for both remote and local server setups, and provides improved guidance on authentication and tool activation.

Visual Studio setup improvements:

• Updated the minimum required version of Visual Studio 2022 to 17.14.9 for compatibility.
• Changed the configuration process to instruct users to create an .mcp.json file in their solution or %USERPROFILE% directory, instead of navigating through Visual Studio's options menu.
• Revised authentication steps: users are now prompted to authenticate via CodeLens and the Copilot Chat window, rather than manually adding an authorization token in the config file. [1] [2]
• Added instructions for enabling tools from the "github" MCP server in Agent mode within the Copilot Chat window. [1] [2]
• Updated the link to the official Visual Studio MCP Guide for accuracy.
