C# docker的内置支持已生成带有错误的dockerfile

My VS 2019 Generated Dockerfile及其下一个代码：

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
WORKDIR /src
COPY ["src/Services/ProductCatalogApi/ProductCatalogApi.csproj", "src/Services/ProductCatalogApi/"]
RUN dotnet restore "src/Services/ProductCatalogApi/ProductCatalogApi.csproj"
COPY . .
WORKDIR "/src/Services/ProductCatalogApi"
RUN dotnet build "ProductCatalogApi.csproj" -c Release -o /app/build

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

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

当我用命令运行Dockerfile时

docker build.

我收到下一个：

在我一整天的时间里，每当我收到错误信息时，我都试图用另一种方式建立自己的形象。请帮助某人

src/Services/ProductCatalogApi/ProductCatalogApi.csproj

在运行它的文件夹中不存在

如果dockerfile与csproj位于同一文件夹中，则应为

COPY ["ProductCatalogApi.csproj", "src/Services/ProductCatalogApi/"]

如果您使用的是docker compose，则路径必须是您尝试运行的docker compose文件的相对路径
