iOS: ResolveAsync callbacks not invoked

[MarkusHorstmann]

It looks like the filter condition in ZeroconfNetServiceBrowser.ResolveAsync is wrong, as the key includes the host name (i.e. myhost._linkplay._tcp.local.):

foreach (var result in results.Where(r => r.Services.ContainsKey(protocol)))
{
    callback?.Invoke(result);
}

should be something like:

foreach (var result in results.Where(r => r.Services.Any(key => key.Contains(protocol)))
{
    callback?.Invoke(result);
}
