[BUG] Rider plugin shows WSL path on native Windows (no WSL installed)

What's Wrong?

When using the /ide command to connect Claude Code to JetBrains Rider on a native Windows 11 installation, the plugin incorrectly reports the project path in WSL format (/mnt/c/...) instead of the native Windows format (C:\...). This causes a path mismatch and prevents IDE integration from working.

What Should Happen?

The IDE should be detected with the default Windows path.

Steps to Reproduce

Steps to Reproduce

1. Install JetBrains Rider on Windows 11 (native, no WSL configured)
2. Open a project located at a Windows path (e.g., C:\Users\username\source\repos\ProjectName)
3. Verify Rider terminal settings:

• Shell path: powershell.exe
• Start directory: Shows correct Windows path
• No WSL toolchain configured in Build/Execution/Deployment settings

1. Install the Claude Code extension in Rider
2. Open any terminal (Alacritty, Windows Terminal, PowerShell, CMD - issue persists across all)
3. Navigate to the project directory:

``powershell
cd C:\Users\username\source\repos\ProjectName
``

1. Start Claude Code:

``powershell
claude
``

1. Type /ide to connect to the IDE

Expected Behavior

Claude Code should detect Rider with the correct Windows path:

Select IDE
Connect to an IDE for integrated development features.

• JetBrains Rider: C:\Users\username\source\repos\ProjectName

Enter to confirm · esc to cancel

Actual Behavior

Claude Code shows a WSL-style path instead:

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.
Found 1 other running IDE(s). However, their workspace/project directories do not match the current cwd.

• JetBrains Rider: /mnt/c/Users/username/source/repos/ProjectName

Enter to confirm · esc to cancel

This causes a path mismatch error because:

• Claude Code's current working directory: C:\Users\username\source\repos\ProjectName
• Rider plugin reports: /mnt/c/Users/username/source/repos/ProjectName

Environment

• OS: Windows 11 (native, no WSL installed)
• Claude Code Version: v2.1.17
• IDE: JetBrains Rider 2025.x
• Terminals tested: PowerShell, CMD, Windows Terminal, Alacritty (issue persists in all)
• .NET CLI Path: C:\Program Files\dotnet\dotnet.exe
• MSBuild: Native Windows SDK path

Workarounds Attempted (None Successful)

• [x] Tried different terminal emulators (PowerShell, CMD, Alacritty, Windows Terminal)
• [x] Verified no WSL configuration in Rider settings
• [x] Reinstalled Claude Code extension in Rider
• [x] Restarted Rider completely
• [x] Confirmed all Rider toolchains point to Windows paths
