.net - mac/linux `dotnet build` 找不到框架 ".NETFramework.."的引用程序集

Question

尝试构建面向 net47 而不是 .netcore 或 .net std 的 Microsoft.NET.Sdk 样式项目时。 dotnet build 将给出有关缺少目标包的错误。 msbuild 将改为工作，但我更愿意使用 dotnet build。有办法吗。

/usr/local/share/dotnet/sdk/2.1.200/Microsoft.Common.CurrentVersion.targets
(1179,5): error MSB3644: The reference assemblies for framework 
".NETFramework,Version=v4.7" were not found. To resolve this, install the
 SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or
 Targeting Pack installed. Note that assemblies will be resolved from the
 Global Assembly Cache (GAC) and will be used in place of reference 
assemblies. Therefore your assembly may not be correctly targeted for the 
framework you intend.

Answer 1

是的。可以使用 nuget 提取目标包。然后添加框架路径覆盖。如果您的目标框架是 .NET v4.7，这里有一个片段可以添加到 Microsoft.NET.Sdk .csproj/.fsproj 的任何位置

  <PropertyGroup Condition="'$(OS)' != 'Windows_NT' AND '$(TargetFramework)'== 'net47'">
    <!-- Make .NET 4.7 reference assemblies available even on Linux -->
    <FrameworkPathOverride>$(NuGetPackageRoot)microsoft.targetingpack.netframework.v4.7/1.0.1/lib/net47/</FrameworkPathOverride>
    <!-- Make sure the additional feed is searched. -->
    <RestoreAdditionalProjectSources>https://dotnet.myget.org/F/dotnet-core/api/v3/index.json</RestoreAdditionalProjectSources>
  </PropertyGroup>

  <ItemGroup Condition="'$(OS)' != 'Windows_NT' AND '$(TargetFramework)'== 'net47'">
      <!-- Make sure the reference assemblies are available -->
      <PackageReference Include="Microsoft.TargetingPack.NETFramework.v4.7"
                        Version="1.0.1" ExcludeAssets="All" PrivateAssets="All" />
  </ItemGroup>
