.net-core - Nuget 包还原失败 Microsoft.Composition 1.0.27

Question

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。

Package Microsoft.Composition 1.0.27 is not compatible with netcoreapp1.1 (.NETCoreApp,Version=v1.1). Package Microsoft.Composition 1.0.27 supports: portable-net45+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=Profile259) One or more packages are incompatible with .NETCoreApp,Version=v1.1.

这是我的 *.csproj 文件

Answer 1

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

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

到您的项目。无法保证它不会在运行时崩溃。
