Issue Title

I'm not able to make the content of appsettings.json from Nuget package to be transformed in .NET Core project.

General

I generate a Nuget package (.NET Standard library) which contains a default appsettings.json.
If I try to add that package to my .NET Core App the file content is being replace instead of transformed or merged.

With .NET FW I was able to use web.config transformations, as described here.

Is there a way to achieve that in .Net Core?

Thank you

Thanks for requesting this, but it is not something we plan to implement.
