Question

我有一个打包到nuget包中的netstandard 2.0库，将其称为A。我引用了该库中的另一个包，将其称为B。

编辑（更多信息）：程序包B依赖于其他nuget程序包，这些程序包是通过SWIG移植的c ++代码。当我在程序包B中引用这些程序包时，.dll，.dylib和.so文件与程序包B的源代码一起安装。当我的netcore应用程序中发生运行时错误时，这些文件“找不到” “

然后，我编写一个引用包A的netcore应用。但是，当我尝试执行该应用时，出现运行时错误，提示它找不到包B的方法。因此，我必须直接引用nuget包B。在netcore .csproj文件中。我没有从netcore应用直接调用程序包B中的代码。它们是通过程序包A抽象的方法调用，程序包A依赖于程序包B中的代码。

我的问题很简单，如何更改.csproj文件，这样就不必在netcore .csproj文件中显式引用程序包B？就像我的标题所暗示的那样，我如何“打包”软件包B，这样就不必在我的网络核心应用中再次引用它了？

.csproj文件示例，以便清楚：

netstandard库

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <Title>My library A</Title>
    <TargetFramework>netstandard2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="B" Version="1.0.0" />
    <PackageReference Include="some_c++_SWIG" Version="1.0.0" />
  </ItemGroup>
</Project>

netcore应用

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <Title>My netcore app</Title>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="A" Version="1.0.0" />

    <!-- Why do I have to include B and SWIG pkg again??? -->
    <PackageReference Include="B" Version="1.0.0" />
    <PackageReference Include="some_c++_SWIG" Version="1.0.0" />
  </ItemGroup>
</Project>

project.assets.json

".NETCoreApp,Version=v2.1": {
  "B/1.0.0": {
    "type": "package",
    "dependencies": {
    "another_package": "1.0.0"
  },
    "compile": {
    "lib/netstandard2.0/B.dll": {}
  },
    "runtime": {
    "lib/netstandard2.0/B.dll": {}
  }
},

    ...

    ]
  },

    ...

    "dependencies": {
      "B": {
        "target": "Package",
        "version": "[1.0.0, )"
      },

这是示例错误消息：（其中c_csharp_metrics具有在软件包B中安装/引用的.dll，.dylib和.so文件）

如何“泡” nuget程序包，这样我就不必重复引用了？
