Vscode-react-native: When debugging via vscode-react-native, the debugger needs to be stopped twice and the packager creates a /.expo/package-info.json file.

[syntax-e]

This may be an issue with my development environment and not vscode-react-native, but the symptoms are only present when using vscode-react-native. Any perspective would be appreciated.

Actual Behavior

1. Create new react native project via react-native init
2. cd into project and open VS Code via code .
3. Open debugger tab and add a new set of React Native debug configurations
4. Hit the 'play' button to Debug iOS
5. (Observe the React Native Packager starts as indicated at the bottom of Visual Studio Code, the app starts in the simulator and the debugger attaches.)
6. Click the stop button on the debugger
7. (Observe nothing happens)
8. Click the stop button on the debugger again
9. (Observe debugger stops and the packager is still running as indicated by the bottom status bar at the bottom of Visual Studio code)
10. Click the stop button on the React Native Packager at the bottom of Visual Studio Code
11. (Observe the packager stops and the /.expo/packager-info.json file is created in the project. )

Expected Behavior

1. Debugger stops when clicking stop the first time
2. No /.expo/package-info.json file is created as this is not an expo project.
3. No mention of expo in output

It happens to me too. But I do get an error the first time I click stop.

Hi @geocachingsyntaxerror and thanks for reporting. I believe, that something has been broken between 1.25 and 1.26 versions of VS Code, because I couldn't reproduce it in 1.25. I will investigate it and let you know about the results.
