默认的netcore docker compose模板是如何工作的[[副本]

dockerize 按钮,它为我创建了以下Dockerfile:

FROM microsoft/dotnet:2.0-runtime AS base
WORKDIR /app

FROM microsoft/dotnet:2.0-sdk AS build
WORKDIR /src
COPY MyProj.sln ./
COPY MyProj.Console/MyProj.Console.csproj MyProj.Console/
COPY MyProj.Core/MyProj.Core.csproj MyProj.Core/
COPY MyProj.Solidity/MyProj.Solidity.csproj MyProj.Solidity/
RUN dotnet restore -nowarn:msb3202,nu1503
COPY . .
WORKDIR /src/MyProj.Console
RUN dotnet build -c Release -o /app

FROM build AS publish
RUN dotnet publish -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "MyProj.Console.dll"]

FROM microsoft/dotnet:2.0-sdk AS build
WORKDIR /src
COPY MyProj.sln ./
COPY MyProj.Console/MyProj.Console.csproj MyProj.Console/
COPY MyProj.Core/MyProj.Core.csproj MyProj.Core/
COPY MyProj.Solidity/MyProj.Solidity.csproj MyProj.Solidity/
RUN dotnet restore -nowarn:msb3202,nu1503

csproj 文件到输出目录,但我没有看到任何 cs 文件夹。整个程序逻辑在哪里?它应该怎么工作?我真的在努力学习它的工作原理,但我就是搞不懂。
