.Net Core: NU1605 Detected package downgrade: System.Reflection.TypeExtensions

When I try Install-Package NBench I'm getting the following error:

Severity Code Description Project File Line Suppression State Error NU1605 Detected package downgrade: System.Reflection.TypeExtensions from 4.3.0 to 4.1.0. Reference the package directly from the project to select a different version. Remark.Performance.NBench.Tests -> NBench 1.2.0 -> NETStandard.Library 1.6.1 -> System.Linq.Expressions 4.3.0 -> System.Reflection.TypeExtensions (>= 4.3.0) Performance.NBench.Tests -> NBench 1.2.0 -> System.Reflection.TypeExtensions (>= 4.1.0) Performance.NBench.Tests D:\\Performance.NBench.Tests.csproj 1

this does not happen I target Net462

We probably just need to upgrade those dependencies in the NBench library itself.

Man, @bcbeatty you are right - this is really quite annoying!

This can temporarily be solved by incorporating the following configuration into any of your affected projects:

<NoWarn>$(NoWarn);CS1591;NU1605</NoWarn>

That NU1605 warning is standard inside most of our projects, which is why I didn't notice this before.

Full example here:
