How to clear WebView cookies in MAUI for windows?

Question

I am trying to logout our webview data.

Clearing cookies in Windows for MAUI doesn't seems to be working.

I am trying with this code:

Windows.Web.Http.Filters.HttpBaseProtocolFilter myFilter = new global::Windows.Web.Http.Filters.HttpBaseProtocolFilter();
                var cookieManager = myFilter.CookieManager;
HttpCookieCollection myCookieJar = cookieManager.GetCookies(new Uri("url"));
                foreach (HttpCookie cookie in myCookieJar)
                {
                    cookieManager.DeleteCookie(cookie);
                }

I am not getting any cookies count.

Hello,

MAUI that targets Windows platform uses WinUI3, you can try getting the native platform view (WebView2) with WebViewHandler on Windows, then clean cookie by CoreWebView2CookieManager.DeleteAllCookies Method. Please refer to the following code:

XML

<StackLayout>  
        <Button Text="ClearCookie" Clicked="Button_Clicked"></Button>  
        <WebView x:Name="MyWebview" Source="XXXX" HeightRequest="400" WidthRequest="400" ></WebView>  
</StackLayout>

Clicking button to clean cookies.

private void Button_Clicked(object sender, EventArgs e)
    {
#if WINDOWS
        var platformView = MyWebview.Handler.PlatformView as WebView2;
        platformView.CoreWebView2.CookieManager.DeleteAllCookies();
#endif
    }
