The global.json with 2.1.4 does not help when using dotnet ef commands in a classlib. You still have to manually add the RuntimeFrameworkVersion to the CSPROJ file on all projects in the solution. If you only add to one NUGET wants to consolidate because some projects are using 2.0.0 and only the ones specified with RuntimeFrameworkVersion use 2.0.5. I only have SDK 2.1.4 installed why does it just not use Runtime 2.0.5 by default?

Why do I have to specify this in ever CSPROJ, what good is the global.json then?

<RuntimeFrameworkVersion>2.0.5</RuntimeFrameworkVersion>
