c# - 无效的框架标识符 Dotnet 还原、docker 构建

Question

当我尝试在我的 dotnet 核心 API 中运行 docker build 时出现此错误:

 Invalid framework identifier ''

这是我的 dockerfile:

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-stretch-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-stretch AS build
WORKDIR /src
COPY Backend/AppManagerAPI/AppManagerAPI.csproj Backend/AppManagerAPI/
COPY Backend/DTO/DTO.csproj Backend/DTO/
COPY nuget.config ./
COPY Build/dependencies.props ./Build
COPY Backend/Database/Database.csproj Backend/Database/
COPY Backend/Service/Service.csproj Backend/Service/
COPY Utilities/Utilities.csproj Utilities/
RUN dotnet restore "Backend/AppManagerAPI/AppManagerAPI.csproj"
COPY . .
WORKDIR "/src/Backend/AppManagerAPI"
RUN dotnet build "AppManagerAPI.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "AppManagerAPI.csproj" -c Release -o /app

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

和完整的错误堆栈:

$ docker build -t appmanager .

我已经尝试了所有我能想到的方法，我想知道它是否与我的 properties.props 文件有关，但是将它复制到容器中没有用。任何帮助，将不胜感激。

更新

这是我的 AppManagerAPI.csproj

问题是我需要复制我的 Directory.Build.props 文件，现在可以正常工作了。刚刚将这一行添加到我的 dockerfile

COPY Directory.Build.props ./
