[待解决问题]
我创建了一个简单的NET CORE Web 应用程序，然后把自动生成的Dockerfile 复制到了.sln文件的同级目录，然后执行了docker build -t test001 . , 镜像可以生成成功。
然后我引用了Newtonsoft，再在项目里引用了它。
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
再执行了docker build -t test001，就报错了。
/src/WebApplication2/Controllers/HomeController.cs(3,7): error CS0246: The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?) [/src/WebApplication2/WebApplication2.csproj]
请问大佬们这个是什么原因
我的Dockerfile
FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80
FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src
RUN cp /etc/hosts /tmp/hosts
RUN mkdir -p -- /lib-override && cp /lib/x86_64-linux-gnu/libnss_files.so.2 /lib-override
RUN sed -i 's:/etc/hosts:/tmp/hosts:g' /lib-override/libnss_files.so.2
ENV LD_LIBRARY_PATH /lib-override
可以随意修改/tmp/hosts了，为了访问nuget服务器，因为有DNS
RUN echo "152.199.4.184 api.nuget.org" >> /tmp/hosts
COPY ["WebApplication2/WebApplication2.csproj", "WebApplication2/"]
RUN dotnet restore "WebApplication2/WebApplication2.csproj"
COPY . .
WORKDIR "/src/WebApplication2"
RUN dotnet build "WebApplication2.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "WebApplication2.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "WebApplication2.dll"]

nuget 引用么, 可以吧你测试的整个项目(或者简化后的)代码都放上来.
然后我引用了Newtonsoft，再在项目里引用了它。
是nuget引用，项目上传了，https://pan.baidu.com/s/1r2ZJdBbQ4e9PI9GByv7IoQ?pwd=74px

@Qoal:
你上传的代码放我本地 build 成功了, 可以吧你失败的build log 也贴上来.

可以build的时候加配置 --progress=plain 在屏幕上保留 container 的log, 也许和你本地网络有关系. nuget 还原失败了.
