• NetCoreWin
• CppLibWin

1. Set the solution active configuration to 'Debug'. To do this, right-click on the solution, then Properties > Configuration Properies > Configuration Manager ...
2. Build CppLibWin
3. Build and run NetCoreWin

• NetCoreWin
• CppLibLinux: this has the exact same codes from CppLibWin

1. Set solution active configuration to Unix.
2. Setup Docker container using the following Dockerfile content

FROM ubuntu

RUN apt-get update && apt-get install -y openssh-server g++ gdb gdbserver
RUN mkdir /var/run/sshd
RUN echo 'root:screencast' | chpasswd
RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

# SSH login fix. Otherwise user is kicked off after login
RUN sed 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' -i /etc/pam.d/sshd

ENV NOTVISIBLE "in users profile"
RUN echo "export VISIBLE=now" >> /etc/profile

EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]

Docker commands

docker build -f <path_to_Dockerfile> -t <image_name> .
docker run -d -P --name test_sshd <image_name>
docker port test_sshd 22

3. Connect the container to Visual Studio Tools > Options > Cross Platform > Connection Manager. Username is root, pass is screencast.
4. Build CppLibLinux
5. Create some folder for the final build

• Copy the built .so from step 4

docker cp test_sshd:/root/projects/CppLibLinux/bin/x64/Unix/libCppLibLinux.so <path_to_final_build_folder>

6. Build NetCoreWin and copy output folder (Unix) to the final build folder Now inside the build folder you have content like this

build_folder
	netcoreapp2.0
		NetCoreWin.dll
		...
	libCppLibLinux.so
	linuxso.Dockerfile

Content of the dockerfiler is

FROM microsoft/dotnet:2.0.4-runtime

COPY ./netcoreapp2.0 /app
COPY ./libCppLibLinux.so /app
WORKDIR /app

CMD [ "dotnet", "./NetCoreWin.dll" ]

7. Final build to docker and verify Inside the final build folder, run commands

docker build -t pinvoke_linux -f linuxso.Dockerfile .
docker run pinvoke_linux
