Reproduction Steps

After running

Command Palette → ".NET Install Tool: Uninstall .NET" → .NET Runtime 7.0.9 x64 | vscode-local

The Output panel reports successful removal:

Attempting to remove .NET 7.0.9~x64.
Uninstalled .NET 7.0.9~x64.

However, the runtime still appears in the uninstall picker UI:

• .NET Runtime 7.0.9 x64 | vscode-local
• .NET Runtime 8.0.24 x64 | vscode-local; Used by dotnet-runtime-library, ms-toolsai.datawrangler

Additional Configuration

The following setting is configured to use the system .NET:

"dotnetAcquisitionExtension.sharedExistingDotnetPath": "C:\\Program Files\\dotnet\\dotnet.exe",
    "dotnetAcquisitionExtension.existingDotnetPath": [
        {
            "extensionId": "ms-dotnettools.csharp",
            "path": "C:\\Program Files\\dotnet\\dotnet.exe"
        },
        {
            "extensionId": "ms-dotnettools.csdevkit",
            "path": "C:\\Program Files\\dotnet\\dotnet.exe"
        }
    ]

Despite this configuration, the stale entries remain visible.

Steps Already Taken

1. Fully closed VS Code (all windows).
2. Ensured no lingering Code.exe or dotnet.exe processes were running.
3. Deleted:

   %APPDATA%\Code\User\globalStorage\ms-dotnettools.vscode-dotnet-runtime
   

4. Deleted:

   %APPDATA%\Code\User\workspaceStorage
   

5. Reopened VS Code.

The globalStorage folder is recreated on startup (empty), but the same runtimes still appear in:

Command Palette → ".NET Install Tool: Uninstall .NET"

6. Verified the actual runtime install directory does NOT contain the runtimes:

   %APPDATA%\Code\User\globalStorage\ms-dotnettools.vscode-dotnet-runtime\.dotnet\
   

The runtime folders (7.0.9~x64, 8.0.24~x64) are not present.

Expected Behavior

• After Successful uninstall
• Automatic deletion of runtime folders
• Restarting VS Code

The runtime should no longer appear in the uninstall UI.
