Detected package downgrade warning (dotnet core, vs 2017)

Question

I have just updated all my nuget packages for my solution (dotnet core 1.1 project).

I am now getting the following warnings and I don\'t really know what they mean.

Answer 1

In my case neither of those properties were set in my csproj files.

I had to tell VS to update those packages via NuGet.

The warnings appeared for me after resolving the warning for explicit reference to implicit dependency .NETCore.App after moving from 1.0 to 1.1.

UPDATE 21/09/17

This also seems to affect upgrades to 2.0, the resolution is the same. Update those packages manually with NuGet. Thanks to IbrarMumtaz for pointing this out!
