What is it?

Visual chatGPT Studio is a Visual Studio extension that connects the IDE to OpenAI, Azure OpenAI, or any OpenAI API-compatible service. Right-clicking selected code in the editor offers commands such as Explain, Add Tests, Find Bugs, Optimize, Add Comments and Translate, and custom before, after or replace commands can be defined in the options.

Beyond inline commands, the extension provides several tool windows: a single-question window, a Turbo Chat window that keeps conversation history and can send open code to the model, a Solution Context window for adding project items to requests, and a Code Review window that generates reviews from Git changes. Turbo Chat also includes agents that can read and edit solution files, query SQL Server databases through connections in Server Explorer, call REST or SOAP APIs, and connect to MCP servers.

The extension supports Visual Studio 2022 and 2026 for Copilot-style inline suggestions, and Visual Studio 2019 is served by a separate package. Authentication works through an OpenAI key, an Azure OpenAI key, or Microsoft Entra ID. Some features rely on function calling, so a compatible model is recommended.

Key features

  • 01Inline editor commands for explaining, testing, bug-finding, optimizing and commenting selected code.
  • 02Turbo Chat window with persistent multi-tab conversation history and image attachments.
  • 03SQL Server agent that runs natural-language SQL against connections configured in Server Explorer.
  • 04API agent for REST and SOAP services, with credentials kept out of the AI context.
  • 05Code Review window that generates reviews from pending Git changes.
  • 06Supports OpenAI, Azure OpenAI with API key or Entra ID, and OpenAI-compatible endpoints.

Use cases

  • Generating unit tests or XML summaries for C# methods while working in Visual Studio.
  • Asking questions about a codebase and having the model read the relevant files in Turbo Chat.
  • Drafting commit messages from pending Git changes before pushing.
  • Querying a development SQL Server database with plain-language requests.

Quick start

  1. 1

    Install the extension from the Visual Studio Marketplace (VS 2022 link in the README)

  2. 2
