[YouthLab]

Hi ,I have a docker file just like this:

FROM microsoft/aspnet:1.0.0-rc1-update1
COPY . /app
WORKDIR /app
RUN ["dnu", "restore"]

EXPOSE 5016
ENTRYPOINT ["dnx", "-p", "Floret-API-Dockerized", "web"]

,
and when i build a image with this,and run the image that i build, i meet those error below (get from "docker logs ")：

Application startup exception: System.IO.DirectoryNotFoundException: Could not find a part of the path "/app/Floret-Sink.Infrastructure/obj/Debug/Floret-Sink.Infrastructure.dll".
