Exceptions

InvalidOperationException

Thrown if CoreWebView2 hasn't been initialized yet, or if the calling thread isn't the thread which created this object (usually the UI thread). See VerifyAccess() for more info. May also be thrown if the browser process has crashed unexpectedly and left the control in an invalid state. We are considering throwing a different type of exception for this case in the future.

ObjectDisposedException

Thrown if Dispose() has already been called on the control.
