This project shows some behaviour differences with System.IO.Pipes.NamedPipeServerStream between .NET Core 2.0 and 2.1-Preview1. Look in Output.md to see this program output from different platforms and versios of .NET Core.

Differences between 2.0 and 2.1-Preview1.

When using .NET Core built from the v2.1-Preview1 branch some new exceptions are thrown.

SocketException

With 2.1-Preview1 System.Net.Sockets.SocketException is thrown on one background thread calling NamedPipeServerStream.EndWaitForConnection. This is new behaviour.

NullReferenceException

On 2.1-Preview1/Debian9/x86 there is also a System.NullReferenceException on a background thread. This comes out of System.Threading.ThreadPoolWorkQueue.Dispatch() and I don't know of any way to catch it. This is an unhandled exception and will cause the program to crash.

ObjectDisposedException

With 2.1-Preview1 there is a System.ObjectDisposedException when calling NamedPipeServerStream.EndWaitForConnection. This was expected behaviour in 2.0 even though this program does not show it.
