我在 mac 上使用带有最新 .Net Core SDK 的 Visual Studio mac。在 Windows 上的 Visual Studio 2017 RC 中，一切正常，但是当我尝试使用 Visual Studio Mac 在 Mac 上恢复 nuget 包时，它会抛出错误。

包 Microsoft.Composition 1.0.27 与 netcoreapp1.1 (.NETCoreApp,Version=v1.1) 不兼容。包 Microsoft.Composition 1.0.27 支持：portable-net45+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=Profile259) 一个或多个包与 .NETCoreApp,Version=v1.1 不兼容。

这是我的 *.csproj 文件

如果这个包是一个真正的 PCL（不使用 bait&switch），你应该可以使用 target fallback 来引用它。尝试添加

    <属性组>
        <PackageTargetFallback>dnxcore50;portable-net45+win8+wp8+wpa81</PackageTargetFallback>
    </属性组>

到你的项目。无法保证它不会在运行时崩溃。

Package Microsoft.Composition 1.0.27仅支持 .NET Framework 4.5、Windows 8、Windows Phone 8.1、Windows Phone Silverlight 8、可移植类库（PCL Profile 259），因此它与 Mac 上的 .Net Core 不兼容

有关包的 Nuget 信息 https://www.nuget.org/packages/Microsoft.Composition/1.0.27

来自支持的回答：

感谢您报告此事。预览版 4 中的 Visual Studio for Mac 忽略 PackageTargetFallback 信息。因此 project.assets.json 文件没有任何导入，这会阻止 NuGet 在应允许时安装 NuGet 包。这个错误应该在下一个版本中修复。
