Remove Parameter Hints Box in Visual Studio Code

Open the menu, chose the command File > Preferences > Settings to open or create a settings.json file where you can modify the behaviour of Visual Studio Code.

In this file, add the following line at an appropriate place:

"editor.parameterHints": false,

In newer version of Visual Studio Code you have to use this instead:

"editor.parameterHints.enabled": false,
