使用dotnet-core项目运行docker时找不到依赖项清单中指定的程序集

我有这样的消息错误:

Error: assembly specified in the dependencies manifest was not found -- package: 'microsoft.aspnetcore.antiforgery', version: '1.1.1', path: 'lib/netstandard1.3/Microsoft.AspNetCore.Antiforgery.dll'

当我运行这个命令时它会发生:

dotnet build -o obj/Docker/publish -c Release
dotnet publish -o obj/Docker/publish -c Release
docker build -t webapi .
docker run -p 80:80 --name api webapi

但在项目中,我可以看到参考

在我的Dockerfile中,我想我已经提供了所有必要的信息:

FROM microsoft/aspnetcore:1.1
ARG source
WORKDIR /
EXPOSE 80
COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["dotnet", "WebApi.dll"]

你知道这种情况会出现什么问题吗？

更新:dotnet restore沟通后变为:

Error: assembly specified in the dependencies manifest was not found -- package: 'microsoft.extensions.dependencyinjection.abstractions', version: '1.1.0', path: 'lib/netstandard1.0/Microsoft.Extensions.DependencyInjection.Abstractions.dll'

它的情况仍然如此.但现在恢复后它不再改变了.
