Why use async void for event handlers

[xcaptain]

I'm learning maui, I found that for event handlers, the function signature is async void, for example:

    async void GotoCustom(object sender, EventArgs e)
    {
        await Shell.Current.GoToAsync(nameof(CustomTipPage));
    }

I think async void is harmful, because the caller can't catch exceptions in it, why not use async Task ?

@xcaptain this is a .NET/C# thing and not .NET MAUI... You can't have async event handlers, so because of that you need to use async void. Just surround it in a try/catch block and you will be safe, if you will

I know async void works, but don't you think async Task is better?

in Blazor, event handler is async Task, see: https://learn.microsoft.com/en-us/aspnet/core/blazor/components/event-handling?view=aspnetcore-8.0

<p>
    <button @onclick="UpdateHeading">
        Update heading
    </button>
</p>

@code {
    private string headingValue = "Initial heading";

    private async Task UpdateHeading()
    {
        await Task.Delay(2000);

        headingValue = $"New heading ({DateTime.Now})";
    }
}

It's an event or a Func<Task> ? I think it doesn't matter
