c# - 运行 dotnet publish -c Release -o out ERROR 时，ASP.NET Core 项目中的 Dockerfile 失败

Question

当我想构建我的项目时，我得到一个错误。

我刚刚安装了docker，DockerFile是标准的，dockerignore是标准的。

我的机器在 Windows 10 x64 上运行。

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "ToDoApp.dll"]

错误：
