This is this issue here: https://github.com/dotnet/sdk/pull/811.

We have already taken a new version of the SDK that fixes this. If you try the latest CLI, this would work for you.

I tried it out.

[sbomer]

Great, thanks!

In which CLI version was that fixed? I am experiencing this problem on 2.0.0-preview1-005977

[Bersam]

I'm still experiencing this on 2.0.3.

[JoseFMP]

Same here. Any news ?!
This is not fixed at all. Why closed?

[livarcocc]

I just tried this on OSX with RID osx-x64.

@Jose-CF can you give us a more detailed repro of your scenario?

[JoseFMP]

@livarcocc I follow the steps from the original post and get the same error. Using dotnet sdk 2.0.2

[livarcocc]

Can you try with the latest release SDK, 2.1.4?

I am seeing the same error when running on docker.

docker logs 679f21c482b02f392e9bb5da197689b42a32e47d41f7b4c6deba3892320d45d9
A fatal error was encountered. The library 'libhostpolicy.so' required to execute the application was not found in '/app/'.

on 2.0.3 and 2.0.5

My Dockerfile

FROM microsoft/aspnetcore
ARG source
WORKDIR /app
EXPOSE 80
COPY ${source:-obj/release/netcoreapp2.0/} .
ENTRYPOINT ["dotnet", "harrier.dll"]

It doesn't work even locally, without invoking in container, but the dll is slightly different.

...\obj\release\netcoreapp2.0> dotnet harrier.dll
A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in '...\obj\release\netcoreapp2.0\'.

EDIT:
replacing COPY ${source:-obj/release/netcoreapp2.0/} . with COPY ${source:-bin/Release/netcoreapp2.0/publish} . solved this problem. I don't understand it though ;)

The contents of the build folder are not supposed to be runnable in production. The way to distribute your app for production is to publish your app and use the contents of the publish folder.
