title: NuGet Installation of EntityFramework
body: <p>I have been doing some testing between VS2015 and VS2017. I created a .NetFrameworkApp and a .NetCoreApp website in both systems. I then installed a couple of packages in all four websites; in particular EntitytFramework. It installed in both VS2015 websites and the VS2017 .NetFrameworkApp website without problem but it wouldn't install in the VS2017 .NETCoreApp website. I got the following error messages.</p>
  
  <ul>
  <li><p>net45 (.NETFramework,Version=v4.5)
  One or more packages are incompatible with .NETCoreApp,Version=v1.1.
  Package restore failed. Rolling back package changes for 'RLSBCWebSite_NC'.
  Time Elapsed: 00:00:01.4470850</p>
  
  <p>Error       Package restore failed. Rolling back package changes for 'RLSBCWebSite_NC'.         0   </p></li>
  </ul>
  
  <p>Anyone any idea why that should be. I am assuming it should install otherwise how would you use CodeFirst etc.</p>
