Repro

IMsalHttpClientFactory factoryHttpClient = new MsalClientFactory("user agent");
IPublicClientApplication client = PublicClientApplicationBuilder
                         .Create("client Id")
                         .WithDesktopFeatures()
                         .WithHttpClientFactory(factoryHttpClient)
                         .WithAuthority("authority")
                         .Build();

var authResult = await client.AcquireTokenInteractive(scopes).WithUseEmbeddedWebView(true)
                        .WithLoginHint("loginHint").WithPrompt(Prompt.NoPrompt)
                       .ExecuteAsync(cancelToken).ConfigureAwait(true);

Expected behavior authResult returns access token

Actual behavior Exception: Method not found: ‘Void Microsoft.Web.WebView2.WinForms.WebView2.add_AcceleratorKeyPressed(System.EventHandler`1<Microsoft.Web.WebView2.Core.CoreWebView2AcceleratorKeyPressedEventArgs>)’.

@bgavrilMS Based on the https://github.com/MicrosoftEdge/WebView2Feedback/issues/1453#issuecomment-871711806, if we upgrade WebView2 SDK version, we’ll have to use OnKeyDown instead of AcceleratorKeyPressed.

Another point is that these events block all shortcut keys like CTRL + V, arrow keys. I think we might need to update the event handler to allow copy, paste, and such. Another alternative is to maybe set WebView2.CoreWebView2.Settings.AreBrowserAcceleratorKeysEnabled which doesn’t disable all the keys.
