我需要一些帮助来解决我在构建ASP.NET项目时遇到的这个问题，该项目引用Docker容器中的本地类库。
我正在使用：

• ASP.NET 6.0语言
• Docker版本20.10.21，构建版本baeda1f
• 互联网软件开发工具包6.0

当我尝试运行docker build .时
出现以下错误：

=> ERROR [build 7/7] RUN dotnet build "ProjectName.csproj" -c Debug -o /app/build                                                                                                                                                                       1.9s

我使用的dockerfile

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY ["ProjectName.csproj", "ProjectName/"]
RUN dotnet restore "ProjectName/ProjectName.csproj"
COPY .. .
WORKDIR "/src/ProjectName"
RUN dotnet build "ProjectName.csproj" -c Publish -o /app/build

FROM build AS debug
RUN dotnet publish "ProjectName.csproj" -c Publish -o /app/publish

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

.csproj文件

<Project Sdk="Microsoft.NET.Sdk.Web">

    <PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>
        <Nullable>enable</Nullable>
        <ImplicitUsings>enable</ImplicitUsings>

    </ItemGroup>

</Project>

有没有关于我让dockerfile在构建时获取.dll包的想法？或者这是一个错误的方法来获取我想要的东西？
我愿意在nuget上托管这个包，但目前这个dockerfile只用于开发目的。
请记住，包在本地位于正确的位置，因为生成项目时使用：
dotnet build ProjectName.csproj
工作正常
P. S. I将包名替换为"PackageName"，将项目名替换为"ProjectName"。
我试着为ASP.NET6.0构建dockerfile，我希望它能通过，但是我得到了一个错误。
