Steps to recreate

I use Docker container to run MonoRemoteDebugger.Server.

Current behavior

Debug process does not start.

Dockerfile:

FROM debian:stretch-20170723

RUN apt-get update && apt-get install -y mono-devel wget unzip

WORKDIR /opt

RUN wget https://github.com/techl/MonoRemoteDebugger/releases/download/v1.3.0/MonoRemoteDebugger.Server.zip && \

I try to debug console application for .NET 4.6.2 or .NET 4.0.

public class Program
{
    public static void Main(string[] args)
    {
        System.Console.WriteLine("Hello world!");
    }
}

I ran the extension under debugger.

System.IO.IOException: DWP Handshake failed.

It always fails for the first time (when need to copy files) and works for the second time. debugSessionStarted in AttachDebugger is false for the first time and true when application has not changed.

It works better under debugger. I think an error happens when multiple tasks run simultaneously in this place:

            var debugSessionStarted = await session.RestartDebuggingAsync(timeout);

            if (!debugSessionStarted)
            {
                await session.TransferFilesAsync();
                await session.WaitForAnswerAsync(timeout);
            }

I think that cancellation token should be used in WaitForAnswerAsync to cancel communication.ReceiveAsync task by timeout.

Can you test after updating mono to latest version? My current mono version is v5.0.1.
