Not seeing output from container

[stianlagstad]

I think I'm experiencing this issue.

• I'm creating a docker image using microsoft/dotnet-framework:4.7.2-sdk.
• The entrypoint is ENTRYPOINT ".\my-executable.exe".
• When I start the container with docker run -it my-image I don't see any output from my executable.
• When I run it directly on my system I see the expected output.
• The executable was created with msbuild my-project.csproj /t:rebuild /p:Configuration=Release /p:PlatformTarget=x64.
• My program has nothing to do with MSYS as far as I can tell.
• If I instead go into a container with docker run -it --entrypoint "powershell" my-image, and then execute .\my-executable.exe while inside the container, I do see the expected output there (inside the container).

Is there something specific I have to do to make sure the output of my executable is actually output to the user running docker run -it my-image?
