Cannot add Microsoft.AspNet.Mvc.Core to classic library

I'm having a classic library that is based on .Net4.6 and I would like to add the nuget-package of the new mvc6. I try doing this using the Package Manager Console. The error is the follwing:

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

Installing the requested System.Runtime is no problem - it works fine:

Install-Package System.Runtime -Pre

And this is the total result:

I'm not sure what it really was... but I changed some points:

  • I had my projects on net461. I changed them back to net451. This removed some warnings in the dependency-graph of the references in the aspnet5-application.
  • After I tried to add Microsoft.AspNet.Mvc.Core and it failed I changed the packages.config manually: I added this line:

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

And after recompiling it seems to work.
