Question

我在mac上使用visual studio mac和最新的.Net Core SDK。在视觉工作室2017年RC在Windows上一切都很好，但是当我尝试使用visual studio mac在mac上恢复nuget包时，它会让我错误。

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）一个或多个程序包与.NETCoreApp，Version = v1.1不兼容。

这是我的* .csproj文件

Answer 1

如果此软件包是真正的PCL（不使用诱饵和开关），您应该能够使用目标回退来引用它。尝试添加

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

到你的项目。无法保证它不会在运行时崩溃。

Answer 2

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配置文件259），因此它与Mac上的.Net Core不兼容

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

Answer 3

来自支持部门的回答：

感谢您报告此事。预览4中的Visual Studio for Mac忽略了PackageTargetFallback信息。所以project.assets.json文件没有任何导入阻止NuGet在允许时安装NuGet包。这个bug应该在下一个版本中修复。
