 # Description
 We propose to add new cases for which the `ProcessFailed` event is raised:

+  1. When a frame-only render process fails. Only subframes within the `CoreWebView2` are impacted in this case (the content is gone and replaced with an error page).
   2. When a WebView2 Runtime child process other than the browser process or a render process fails. The app can use these process failures for logging and telemetry purposes.
 
 We also propose extending the `ProcessFailedEventArgs` to provide additional information about the process failure:
