In addition we should add a property where you can check if the CoreWebView2 is closed or not. This way end dev's asynchronous code that may be in progress when the profile is deleted can check if the CoreWebView2 has closed and take appropriate action.

/// Returns TRUE if the CoreWebView2 is closed. Once closed, CoreWebView2 
/// events will no longer be raised and methods will immediately return failure
/// unless otherwise noted in the API documentation. This property will continue
/// to work after the CoreWebView2 is closed.

I think do not need this function. Because, close webview and Closed event handle function called are in a same therad and a same loop. So, if the Closed event handle function called, the user has known the webview has been closed, they can record a flag in this function; if before Closed event handle function called, the webview is always still alive.

/// The CoreWebView2 has closed because its corresponding Profile has been or
/// marked as deleted.

The two other cases we should add here (we can get the urgent work's implementation in first, and the less urgent parts implementation in a later PR) are for normal webview2 shutdown, and for browser process crash. Maybe this:

/// The CoreWebView2 has closed because the corresponding
/// CoreWebView2Controller had its Close method called either
/// explicitly or implicitly.
COREWEBVIEW2_CLOSED_REASON_SHUTDOWN,

/// The CoreWebView2 has closed because its browser process
/// crashed. The Closed event will be raised after the ProcessFailed
/// event is raised.
COREWEBVIEW2_CLOSED_REASON_BROWSER_PROCESS_FAILURE,

Ok, I will create a work item to trace this things.

Do I need to add those to the API SPEC, or add them one by one in a later PR?
