get_FrameId

The unique identifier of the main frame.

public HRESULT get_FrameId(UINT32 * value)

It's the same kind of ID as with the FrameId in CoreWebView2Frame and via CoreWebView2FrameInfo. Note that FrameId may not be valid if CoreWebView2 has not done any navigation. It's safe to get this value during or after the first ContentLoading event. Otherwise, it could return the invalid frame Id 0.
