After downloading Mono 4.2 (stable release) for Ubuntu, I got errors of importing System Libraries in a C# program to establish a connexion with APNS servers (Apple Push Notification).

To build, I use xbuild command (no parameters).

NB : The build is successfully executed on Windows 10.

Change the target framework to .NET 4.5 and you should see it works.

Mono does not support .NET 4.5.2 yet.

Can be also just not installed proeprversion of .NET (also older one as it was in my case). Anyway switching target framework just helped. Thx – Walleyed 9/6, 2017 at 10:29

Before making any modification on your code please check:

apt-cache policy monodevelop
apt-cache policy mono-complete

I had such an issue which solved by checking and re-installing mono-complete packages
