$ .paket/paket.exe why --group netcore Microsoft.NETCore.DotNetHostPolicy
Paket version 5.92.3
NuGet Microsoft.NETCore.DotNetHostPolicy is a transitive dependency.
It's a part of following dependency chains:

-> Microsoft.NETCore.App
  -> Microsoft.NETCore.DotNetHostPolicy

Performance:
 - Runtime: 13 seconds

There is no reason for paket to resolve a 2.X version of Microsoft.NETCore.DotNetHostPolicy it should resolve https://www.nuget.org/packages/Microsoft.NETCore.DotNetHostPolicy/1.1.0 because Microsoft.NETCore.DotNetHostPolicy (>= 1.0.5) is requested by Microsoft.NETCore.App.

Also when I look at https://www.nuget.org/packages/dotnet-mergenupkg it seems fundamental to use different versions of the same package to support multiple dotnet-sdks....

Expected behavior

Paket should choose the correct versions.

Actual behavior

Paket uses the wrong versions

Known workarounds

Specifying all dependencies as direct dependencies?

Start by reproducing the netcore group resolution from the issue body with Paket 5.92.3, then compare the resolved Microsoft.NETCore.DotNetHostPolicy versions and the output of paket why. Trace the dependency-resolution behavior responsible for selecting version 2.0; done means the reported constraints select the compatible 1.1.x version without requiring every dependency to be declared directly.
