Question

i run dockerfile

#servercore its mine tag
FROM  servercore 
COPY ./prog./work/prog
WORKDIR /work
CMD ["cmd.exe", "/c", "start /b C:\\work\\prog\\prog.exe"]

then inside of container i type tasklist and see in this case my program doesn`t work

Also i tried to run exe inside windows servercore with terminal and my program is fully working, which can be seen in memory in the task manager

How can і run exe by dockerfile ?

It might have happened because when you are trying to start your app.exe from different path then your app. It might throw some exception because app does not see all dependencies/resources etc. You should change your workdir from WORKDIR /work to WORKDIR /work/prog and in CMD ./prog.exe.
