title: How do I remove the value of the settings for VSIX when I uninstall it
body: <p>I have followed the steps under <a href="https://docs.microsoft.com/en-us/visualstudio/extensibility/extending-user-settings-and-options?view=vs-2019" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/visualstudio/extensibility/extending-user-settings-and-options?view=vs-2019</a> to create settings for my extension but seem after I uninstall and re-install the extension, the settings value still the one I configured before rather than the default value, do I doing this one in the wrong way or?
  Can someone give some advice on that? Thanks!</p>
