NuGet强制安装忽略版本

NPM的家伙，不熟悉NuGet的东西

我试着

  Install-Package UnmanagedExports

,

Installing 'UnmanagedExports 1.2.6'.
Successfully installed 'UnmanagedExports 1.2.6'.
Adding 'UnmanagedExports 1.2.6' to my-project.
Uninstalling 'UnmanagedExports 1.2.6'.
Successfully uninstalled 'UnmanagedExports 1.2.6'.
Install failed. Rolling back...
Install-Package : Could not install
Install-Package : Could not install package 'UnmanagedExports 1.2.6'. You are trying to install this package 
into a project that targets '.NETCore,Version=v4.5.1', but the package does not contain any assembly references 
or content files that are compatible with that framework. For more information, contact the package author.

   At line:1 char:2
    +  Install-Package UnmanagedExports 
    +  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

可能这个库只是没有赶上指示最新的。net版本，我希望如此，因此我将强制安装。

你能告诉我怎么做吗?

我解压缩了nupkg，并调查了内容，但没有线索。谢谢。
