Question

我有一个基于.Net4.6的经典库，我想添加新mvc6的nuget-package。我尝试使用程序包管理器控制台执行此操作。错误如下：

Install-Package : Failed to add reference to 'System.Runtime'. Please make sure that it is in the Global Assembly Cache.
At line:1 char:1
+ Install-Package Microsoft.AspNet.Mvc.Core -Pre
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Install-Package], Exception
    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand

安装请求的System.Runtime没问题 - 它运行正常：

Install-Package System.Runtime -Pre

这是总结果：

知道这可能是什么问题吗？

Answer 1

我不确定它到底是什么......但我改变了一些观点：

我在net461上有我的项目。我把它们改回net451。这删除了aspnet5-application中引用的依赖关系图中的一些警告。
我尝试添加Microsoft.AspNet.Mvc.Core后失败了，我手动更改了packages.config：我添加了这一行：

<package id="Microsoft.AspNet.Mvc.Core" version="6.0.0-rc1-final" targetFramework="net451" />

重新编译后，它似乎有效。

无法将Microsoft.AspNet.Mvc.Core添加到经典库
