System.PlatformNotSupportedException: Sockets on this platform are invalid for use after a failed connection attempt

Hi,
I'm getting an error after upgrade EnyimMemcachedCore to 2.1.7 (.NET Core 2.1).

The error occurs when run it on Linux machine in docker, memcached served on another Linux machine if it matters. Running application locally on Windows it works well (no docker).

And it was working fine on version 2.1.2 targeting on .NET Core 2.0 both Linux and Windows.

Sorry, fixed it in EnyimMemcachedCore 2.1.8.
