Bug Description

The Claude Code plugin, version 0.1.9-beta, available for install in Jetbrains Rider Marketplace will not connect to the Windows version of Jetbrains Rider.

Steps to Reproduce

1. Install WSL via Powershell by running wsl --install
2. Set default WSL version in Powershell by running wsl --set-default-version 2
3. Run WSL -d Ubuntu
4. Run sudo apt update && sudo apt upgrade
5. Run sudo apt install nodejs
6. Install Claude using npm install -g @anthropic-ai/claude-code
7. Change to project directory
8. Start Claude
9. Open Jetbrains Rider version 2025.1.3 on Windows
10. Install Claude Code plug in 0.1.9-beta
11. Configure and launch Claude Code plugin using icon in the IDE
12. Check the project path is the same as the Claude Code path within WSL
13. Type /ide in the Claude Code terminal of the IDE

Expected Behavior

Listing Jetbrains Rider as an available IDE and defaults to that option so that the IDE can be connected to

Actual Behavior

No IDE's available. Select IDE Connect to an IDE for integrated development features. No available IDEs detected. Make sure your IDE has the Claude Code extension or plugin installed and is running.

Additional Context

If I install and launch Rider from within the Linux distro then Claude will connect to the Linux version of the IDE. This issue seems limited to the WIndows IDE.

I've checked the WSL file path mappings in Rider by going to Settings > Tools > Claude Code [Beta]. They seem fine.

I've restarted Rider multiple times as per the support guide provided by Fin.
