LINQPad 9 is now RTM! Packed with dozens of new features, this is the biggest major update yet. Windows + macOS https://t.co/mGO9AMlCdj

@egvijayanand Did you accidentally toggle the option on the menu? Ctrl+shift+e

This LINQPad script plays AI models against one other in chess. Shown is the leaderboard after round-robin tournaments between 10 popular models. Can you guess the winner?

@terryaney It should work now in 9.9.9. Let me know.

[LINQPad·Joe Albahari @linqpad]

@terryaney No, I wasn't aware of this. This is caused by a bug in the way CC handles settings. I'll look into whether there's a workaround.

[LINQPad·Joe Albahari @linqpad]

@thermous LINQPad uses XPF rather than native Avalonia: this allows a pure WPF build on the Windows side, but restricts Avalonia library options. I ended up using xterm.js inside WebView2/WKWebView. If I one day do a full Avalonia build, this library looks like the way forward.

The Gold Standard in coding agents - Claude Code - is now available inside LINQPad! Experience the real Claude Code CLI, doing its Claudy things to a LINQPad script, with access to 20+ LINQPad tools. Uses your existing high-value Pro or Max plan. https://t.co/7Cv4sBUlz6

@terryaney Understood. As a matter of interest, have you calculated how much Copilot will cost you for general programming one week from now? For me, it's ~$1000/month (vs $100/month for Claude Code). I anticipate a wave of Copilot refugees washing up on the shores of Claude Code and Codex!

[LINQPad·Joe Albahari @linqpad]

@terryaney LINQPad's AI Chat window is now fully agentic with Copilot - it directs requests to Copilot SDK which in turn calls the Copilot CLI - so you should see similar capabilities (although with a different UI).

[LINQPad·Joe Albahari @linqpad]

@egvijayanand Most likely, your WebView2 is temporarily hosed due to a MS automatic update. Restart your PC and let me know if the issue persists.

[LINQPad·Joe Albahari @linqpad]

@terryaney @Copilot Beta runs side-by-side and is side effect free in terms of installation and residue. RTM is now out, but I still suggest you run beta because amazing new features will be added to Copilot integration in next few days!

[LINQPad·Joe Albahari @linqpad]

LINQPad now works with your @copilot account! Use Copilot as the backend for all of LINQPad's AI features: coding agent, chat, code completion, and SQL-to-LINQ conversion. No extra account needed, fully integrated, all native LINQPad prompts.

[LINQPad·Joe Albahari @linqpad]

@RickStrahl @Copilot Yes. The Copilot SDK has patchy documentation, so I wrote an MCP server to give Copilot & Claude Code access to ILSpy (for decompilation) and LINQPad (to run experiments). With this, it figured how to use the SDK within minutes, explained it to me, and wrote the wrapper!

[LINQPad·Joe Albahari @linqpad]

@egvijayanand Thanks - this will be fixed in the next build.

[LINQPad·Joe Albahari @linqpad]

New/improved JavaScript interop in the latest LINQPad beta: Now you can easily access the JavaScript ecosystem from C# - or ask AI to do it for you!

[LINQPad·Joe Albahari @linqpad]

@egvijayanand That makes sense. I'll get a fix into today's beta.

[LINQPad·Joe Albahari @linqpad]

@egvijayanand I've managed to repro this with a .txt file (and will fix this in the next build), but not a .linq file. Does it happen with all scripts?

[LINQPad·Joe Albahari @linqpad]

@terryaney Yes - this is for consistency (alt+cursor keys scroll results in all directions, now). Use Ctrl+Shift+Alt modifier to move lines up/down. If you prefer the old shortcuts, this is very easy to customize. Go to settings or press Ctrl+F6.

[LINQPad·Joe Albahari @linqpad]

@NimaAra It shouldn't override the API key if you specify a different instance name. Are you sure it's actually using the same slot? (You can check in Password Manager)

[LINQPad·Joe Albahari @linqpad]

@egvijayanand There's now a Util.Markdown method. Does this help?
