Expand description

A continuation of the ICoreWebView2ProcessFailedEventArgs interface.

Required methods

The reason for the process failure. The reason is always COREWEBVIEW2_PROCESS_FAILED_REASON_UNEXPECTED when ProcessFailedKind is COREWEBVIEW2_PROCESS_FAILED_KIND_BROWSER_PROCESS_EXITED, and COREWEBVIEW2_PROCESS_FAILED_REASON_UNRESPONSIVE when ProcessFailedKind is COREWEBVIEW2_PROCESS_FAILED_KIND_RENDER_PROCESS_UNRESPONSIVE. For other process failure kinds, the reason may be any of the reason values.

The exit code of the failing process, for telemetry purposes. The exit code is always 1 when ProcessFailedKind is COREWEBVIEW2_PROCESS_FAILED_KIND_BROWSER_PROCESS_EXITED, and STILL_ACTIVE (259) when ProcessFailedKind is COREWEBVIEW2_PROCESS_FAILED_KIND_RENDER_PROCESS_UNRESPONSIVE.

Description of the process assigned by the WebView2 Runtime. This is a technical English term appropriate for logging or development purposes, and not localized for the end user. It applies to utility processes (for example, “Audio Service”, “Video Capture”) and plugin processes (for example, “Flash”). The returned processDescription is empty if the WebView2 Runtime did not assign a description to the process.

The collection of FrameInfos for frames in the ICoreWebView2 that were being rendered by the failed process. The content in these frames is replaced with an error page. This is only available when ProcessFailedKind is COREWEBVIEW2_PROCESS_FAILED_KIND_FRAME_RENDER_PROCESS_EXITED; frames is null for all other process failure kinds, including the case in which the failed process was the renderer for the main frame and subframes within it, for which the failure kind is COREWEBVIEW2_PROCESS_FAILED_KIND_RENDER_PROCESS_EXITED.
