System.Net.NetworkInformation.Ping does not work in MauiApp on iOS Device, .net 7

[skima74]

Description

Cant seem to use the System.Net.NetworkInformation.Ping class on an ios device.
The deployment works fine on windows.
On the iOS device the code reports the following error at run time:

2022-12-30 10:53:41.989 Xamarin.PreBuilt.iOS[1496:228454] Could not resolve assembly System.Net.Ping.resources, Version=7.0.0.0, Culture=en-AU, PublicKeyToken=null.

Steps to Reproduce

Created a standard new MauiApp, added a button and entry to test the Ping functionality.
The code from the Ping test is taken directly from the MS docs :

@skima74 does it work on Android without any issues as I have bumped into some similar Crashes when trying to ping my own api?

[skima74]

I checked it on the default Android Emulator (Pixel 5, Api 33). Same issue - looks like the runtimes are missing for the mobile platforms, or non-Windows platforms.

[EdwardMcFlurry]

Can we get the Maui Team to take a look at this issue and/or perhaps provide some workarounds?

There was an Android issue around ping that should be fixed with #79076.

The iOS issue sounds more like a network/permission issue to me. Can you please try with a publicly accessible IP like 8.8.8.8 ?

This issue has been marked needs-author-action and may be missing some important information.

This issue has been automatically marked no-recent-activity because it has not had any activity for 14 days. It will be closed if no further activity occurs within 14 more days. Any new comment (by anyone, not necessarily the author) will remove no-recent-activity.

This issue will now be closed since it had been marked no-recent-activity but received no further activity in the past 14 days. It is still possible to reopen or comment on the issue, but please note that the issue will be locked if it remains inactive for another 30 days.
