System.Net.Dns.GetHostAddresses hangs after update to 5.0.0.2083 (works on 1931)

Question

The following code worked for me for 2 years:
var addr = System.Net.Dns.GetHostAddresses(url);

After updating Xamarin (and Essentials) to 5.0.0.2083 it's just hanging there until app crashes.

Any ideas/workaround?

Hi @JarvanZhang , thank you for your attention.
I forgot to mention that i also updated VS (pro) to 16.10.4

The issue was the emulator had no internet access, this is weird because as i said - before those upgrades everything worked fine.
It looks like that one of the updates messed the emulators configuration.

After creating a new emulator everything went back to track.
So i updated Xamarin back to latest and still worked, probably the VS updated messed the emulator configs.

Thanks.
