我有两个web服务的解决方案。该解决方案中的所有项目都设置了net6.0目标框架。本地构建通过，没有任何错误。我正试图从dockerfile建立一个docker映像，并在dotnet build阶段得到很多CS0246错误。
我dockerfile:
FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS env
WORKDIR /app
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY . .
RUN dotnet restore
COPY . .
RUN dotnet build -c Debug -o /app/build --no-restore
FROM build AS publish
RUN dotnet publish "My.Api/My.Api.csproj" -c Debug -o /app/publish --no-build --no-restore
FROM env AS final
WORKDIR /app
COPY --from=build /app/publish ./
EXPOSE 5000
ENV ASPNETCORE_URLS=https://+:5000
ENV ASPNETCORE_ENVIRONMENT=Development
ENTRYPOINT ["dotnet", "My.Api.dll"]
我从解决方案目录调用的命令:docker build . -t my.api:1.0.0 -t my.api:lastest -f ./My.Api/Dockerfile --no-cache
下面是该命令的部分输出:

I tried to:
- 将dockerfile放入解决方案文件夹
- 带和不带
--no-cache参数运行 - 只执行
COPY命令，搜索容器内的文件。它们都在那里
我找到了解决方案。docker。net环境中有一个bug。它只是不工作与ImplicitUsings。
删除该标签并手动添加使用可以使其工作。全局使用也可以。
