Dear Ari,
> Is it possible to block the use of the right mouse button using the WebView?
Yes, we can implement a new method to do it. It is not currently implemented.
ICoreWebView2Settings* settings; // a reminder for me
controller->get_Settings(&settings);
settings->put_AreDefaultContextMenusEnabled(FALSE);
> What if WebView only works with Microsoft Edge?
Yes, WebView is developed by Microsoft and uses the Microsoft required DLLs.
> with Chrome does it work?
No, sorry. Chrome does not provide something similar yet.
