get_AssociatedFrameInfos

The collection of associated FrameInfos which are actively running (showing or hiding UI elements) in this renderer process.

public HRESULT get_AssociatedFrameInfos(ICoreWebView2FrameInfoCollection ** frames)

AssociatedFrameInfos will only be populated when this CoreWebView2ProcessExtendedInfo corresponds to a renderer process. Non-renderer processes will always have an empty AssociatedFrameInfos. The AssociatedFrameInfos may also be empty for renderer processes that have no active frames.
