Infinite Loop When Asking For .gitignore example in C#

[Christopher-Loyd]

When asking CoPilot: "example .gitignore file for C# project" CoPilot will begin building the .gitignore file in chat but then put itself in an infinite loop somewhere in the file creation, continually reproducing the same line. This has been reproducible on my machine. I needed to kill VSCode and start a new chat to get CoPilot working again each time.

• Copilot Chat Extension Version: v1.244.0
• VS Code Version: 1.92.2 (system setup)
• OS Version: 23H2 (OS Build 22631.4037)

Steps to Reproduce:

1. Ask "example .gitignore file for C# project"
2. Wait for infinite loop output
3. ????
4. Don't Profit

Below is one of the examples it spit out, however, where it decides to enter its infinite loop changed each time I ran it:

@joyceerhl @digitarald I can also reproduce this issue in the chat-panel without using /new.
