Assemblies not found when running application using microsoft/aspnetcore image

If you are having an issue with microsoft/aspnet, please open an issue on https://github.com/Microsoft/aspnet-docker. This repository is for microsoft/aspnetcore and microsoft/aspnetcore-build.

Steps to reproduce the issue

(e.g. copy your Dockerfile or docker-compose.yml file here)

FROM microsoft/aspnetcore-build:2.0.0 AS builder

WORKDIR /SawneeMed.API.Web
COPY SawneeMed.API.Web/SawneeMed.API.Web.csproj .
RUN dotnet restore
COPY SawneeMed.API.Web/ .
RUN dotnet build -c Release -o out

FROM microsoft/aspnetcore:2.0.0

WORKDIR /SawneeMed.API.Web
COPY --from=builder /SawneeMed.API.Web/out/ .
ENTRYPOINT ["dotnet", "/SawneeMed.API.Web/SawneeMed.API.Web.dll"]

Expected behavior

A running webapi container

Actual behavior

Build process completes, this error happens when trying to run my web app:

Error:
  An assembly specified in the application dependencies manifest (SawneeMed.API.Web.deps.json) was not found:
    package: 'Swashbuckle.AspNetCore.Swagger', version: '1.0.0'
    path: 'lib/netstandard1.6/Swashbuckle.AspNetCore.Swagger.dll'

Additional information (e.g. issue happens only occasionally)

I found this issue that seems similar, but the given advice was to use the microsoft/aspnetcore image to run the application. As you can see, I am using that image. I've also tried building application using the 'linux-x64' runtime identifier, but then I'm hitting this other issue which they claim to have been fixed months ago.
