Add support for Visual Studio 2026 Integration

Preflight Checklist

• I have searched existing requests and this feature hasn't been requested yet
• This is a single feature request (not multiple features)

Problem Statement

I rely on Visual Studio 2026 for C++ and Win32 system-level development (e.g., global hooks, drivers) because its debugger and toolchain are superior to VS Code/JetBrains for this specific stack.

Currently, claude-code only offers native plugins for VS Code and JetBrains. To use Claude Code with Visual Studio 2026, I am forced to run it in a detached terminal window. This creates significant friction:

1. No Integrated Diff: I have to review complex code changes in the terminal text stream instead of Visual Studio's native Diff/Merge GUI.
2. No Context Awareness: Claude cannot automatically see my open files, selected code, or compiler diagnostics (error list). I have to manually copy-paste errors or file contents.
3. Context Switching: Constant Alt-Tab between the IDE and the terminal breaks flow.

Proposed Solution

Create a native VSIX extension for Visual Studio 2026 that provides feature parity with the existing VS Code extension:

1. Integrated Chat Panel: A dockable tool window within VS 2026.
2. Native Diff Viewing: When Claude proposes changes, show them using Visual Studio's native Diff window for review/accept/reject.
3. Context Synchronization: Automatically share active file content, cursor selection, and build errors/warnings with the agent.
4. /ide Command Support: Allow terminal sessions to link to the active VS instance.

Alternative Solutions

• Current Workaround: Running claude CLI in an external terminal (Windows Terminal) or the VS Integrated Terminal. This is suboptimal due to the lack of GUI diffs and auto-context.
• Switching IDEs: Trying to move the C++ project to VS Code just for Claude support, but this sacrifices the advanced debugging capabilities of Visual Studio 2026 required for Win32 development.

Use Case Example

Scenario: Debugging a Win32 Keyboard Hook

1. I am debugging a SetWindowsHookEx crash in hook.cpp inside Visual Studio 2026.
2. I hit a breakpoint where a variable pKey is null.
3. Ideally: I open the Claude Code panel inside VS, select the crashing function, and ask: "Why is pKey null here?".
4. Claude analyzes the selected code and the current file context automatically.
5. Claude proposes a fix (adding a null check).
6. I click "Review", and VS opens its native Diff window showing the change.
7. I click "Accept", and the code is updated without me ever leaving the IDE.

Additional Context

Visual Studio remains the de-facto standard for Windows native development. Ignoring it excludes a large portion of systems engineers and C++ game developers.

Yes please, just using the integrated terminal is of limited use, and trying to deal with game projects in VS Code is not a sacrifice worth making.

I had a long Pro Plan session with Claude CLI trying to do this.. I installed Claude Code Extension for Visual Studio. That got me as far as Claude Code window in VS2026. Anything I type pops up the Github Copilot Hub. There it looks as if I can 'Manage Models' 'Bring my own model' . Choices include Anthropic. At which point it asks for an API key. I don't have one. A separate billing process involving credits. Might that work?, I don't fancy trying even $5 to find out. Back to CLI .

It's hard to pitch Claude Code to my boss without proper VS integration in my .NET environment

Windows game dev is almost exclusively C++ and Visual Studio. I wish there was an extension.

It would be really a breaktrhough. Hate AI tools being released for VS Code and not for VS!

It's so weird that Claude Code isn't available for Visual Studio 2022 or 2026 yet. VS Code is nice when I'm using it, but 90% of my work is in the Visual Studio IDE. The workarounds we have to come up with are annoying.

Dear god, yes please.
We have half the team on vs code, I'm using copilot on Visual Studio...having the option to just use claude code and add MCP-Servers using the same config as in visual studio code(Visual studio simply doesn't support prompts the same way and complains about "version" and other json properties which literally don't invalidate the rest of the json config values).
I'm sure Anthropics being so close with Microsoft SHOULD be able to bring the same user experience to Visual Studio in fact I can't understand why Microsoft released Visual Studio 2026 with such subpar support for these features in the first place compared to VSCode.

I was using Claude CLI this morning to review some code and then add features, including an additional form button. It successfully proposed the changes, redesigned the form, then after I had backed up, accepted the changes and given the go ahead it ran the build and debug. The IDE was open at the time so I could have the windows open side by side. Not ideal but gave a hint of what could be achieved if this integration request was implemented.

Adding my voice here. I'm a Max subscriber using Visual Studio 2026 on Windows 10 for cross-platform Avalonia UI development. Getting Claude Code working in VS required a community extension, a WinGet install, manually copying claude.exe to a different directory because the extension couldn't find it, registry edits for terminal embedding, and several hours of troubleshooting. The tool is powerful once it's running, but the lack of native VS support makes the onboarding experience painful. Full Visual Studio should not be treated as second-class to VS Code.

Full stack development uses azure, aspire, avalonia and a host of complex tools. Windows 10 , especially among enterprise developers is the de-facto standard. Your own Claude Code Max ai wonders why you have neglected the huge market that is currently under-served. If you wont listen to us, listen to Claude Code using a MAX subscription..
