GetProcessExtendedInfos

Gets a snapshot collection of ProcessExtendedInfos corresponding to all currently running processes associated with this CoreWebView2Environment excludes crashpad process.

public HRESULT GetProcessExtendedInfos(ICoreWebView2GetProcessExtendedInfosCompletedHandler * handler)

This provides the same list of ProcessInfos as what's provided in GetProcessInfos, but additionally provides a list of associated FrameInfos which are actively running (showing or hiding UI elements) in the renderer process. See AssociatedFrameInfos for more information.
