.Net 核心预发布版本上框架程序集的间接依赖

Question

我正在用 .Net Core 的预发布版本做一些实验。

我正在使用 1.0.0-preview4-004071 版本的 .Net Core。安装 .NET Core SDK，在 C:\Program Files\dotnet\shared\Microsoft.NETCore.App 中创建 1.0.3 文件夹并添加二进制文件对于相同的构建版本（全部从 https://github.com/dotnet/cli#installers-and-binaries 下载）。

我的 *.csproj 文件是：

<Project ToolsVersion="15.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Import Project="$(MSBuildExtensionsPath)$(MSBuildToolsVersion)\Microsoft.Common.props" />

<PropertyGroup>
   <OutputType>Exe</OutputType>
   <TargetFramework>netcoreapp1.1</TargetFramework>
</PropertyGroup>
<ItemGroup>
   <Compile Include="**\*.cs" />
   <EmbeddedResource Include="**\*.resx" />
</ItemGroup>
<ItemGroup>
   <PackageReference Include="Microsoft.NETCore.App">
   <Version>1.0.3</Version>
</PackageReference>
<PackageReference Include="Microsoft.NET.Sdk">
   <Version>1.0.0-alpha-20161104-2</Version>
   <PrivateAssets>All</PrivateAssets>
</PackageReference> 
</ItemGroup>        
<Reference Include="System.Collections.Specialized"/>
<Reference Include="System.Collections.NonGeneric">
   <SpecificVersion>False</SpecificVersion>
   <HintPath>Lib\System.Collections.NonGeneric.dll</HintPath>
</Reference>
<Reference Include="System.Resources.ResourceManager"> 
   <SpecificVersion>False</SpecificVersion>  
   <HintPath>Lib\System.Resources.ResourceManager.dll</HintPath>
</Reference>
</ItemGroup>
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
</Project>

在 Lib 文件夹下，我有来自同一版本的 DLL 副本。

我正在尝试使用 System.Collections.Specialized 和 System.Collections.NonGeneric DLL（试图从默认路径和Lib 文件夹）但收到这样的警告：

C:\Program Files\dotnet\sdk.0.0-preview4-004071\Microsoft.Common.CurrentVersion.targets(1909,5): warning MSB3268: The primary reference "System.Collections.NonGeneric" could not be resolved because it has an indirect dependency on the framework assembly "System.Runtime, Version=4.0.20.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v4.0". To resolve this problem, either remove the reference "System.Collections.NonGeneric" or retarget your application to a framework version which contains "System.Runtime, Version=4.0.20.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".

如果我是对的，问题是 msbuild 无法找到正确的程序集并查看不正确的路径。

如何修复程序集路径查找？

必须将对 .Net Core 的引用添加为包而不是像这样的 DLL：

<PackageReference Include="System.Reflection.Emit">
  <Version>4.0.1</Version>
</PackageReference>
