Running a 'Docker Compose' from Visual Studio includes a reference to docker-compose.vs.debug.g.yml which causes COPY command not to work properly

Question

The Dockerfile COPY command is not actually copying a file into a container's file system when it was run via Visual Studio 'Docker Compose' start button (with or without debugging). Dockerfile excerpt:

FROM base AS final
WORKDIR /app
COPY ["src/My.UserProfile.Api/test.txt", "/usr/local/bin/"]

After I ran 'Docker Compose' from Visual Studio I inspected the container's file system in order to find a file that was supposed to be copied into (test.txt) - but it was missing.

So I've observed the docker-compose up command logged in my Output window, and tried to run it from command prompt instead of from Visual Studio.

That gave the same result - the file was still missing.

However, when I remove reference to docker-compose.vs.debug.g.yml everything works as expected.

Any idea why would -f "C:\dev\source\repos\userprofile-service\obj\Docker\docker-compose.vs.debug.g.yml" cause these issues?
