Reporting two unrelated thing as one bug.

I can't replicate the WebView bug mentioned in the title on Windows 11. In seems to be behaving correctly and opening the links in the browser. It is possible that you have uninstalled Edge, which could create problems like the one you are seeing.

The ContentDialog not changing size is not a bug with WinUI2 or the System XAML. In fact it is working as you asked. Maybe don't set the MaxWidth of the ContentDialog.

So it seems that the corner radius being set with the WinUI styles is causing this issue. If you add the following to your ButtonBase_OnClick function before opening the content dialog, it works (note that you need to use the API contract since CornerRadius is not available on every Windows 10 version):

if(ApiInformation.IsApiContractPresent("Windows.Foundation.FoundationContract", 7))
{
    _verificationDialog.CornerRadius = new CornerRadius(0);
}

@chingucoding when will you fix it please?

@HppZ I am not working for Microsoft so I can't tell you when this will be fixed. The problem is that the issue probably somewhere in WebView which means there isn't much one can do here beside using the workaround.

@chingucoding Thank you.

This is a duplicate of #5299 The issue is in system xaml and has been fixed for later versions of windows however is still present for some Win10 versions. Resolving this issue is challenging and Chingucoding's suggestion of removing the corner radius is the best work around we have.
