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

The issue for me was that I had packages installed locally that were of higher versions than my projects referenced. If you go to Tools > NuGet Package Manager > Package Manager Settings > General > Clear All NuGet Cache(s) then rebuild your solution it'll install the packages referenced and the errors will go.
