I\'ve been looking for any way to set the CopyToOutput attribute to true for content files I\'m including in a nuget package built in VS2017 from a .Net Standard Library pro
see https://github.com/NuGet/NuGet.Client/pull/1450 Allow specifying copyToOutput and flatten as Metadata on Content items when packing sdk csproj
You'll need to set PackageCopyToOutput to true in the source csproj for the content.
true
and once build the package, it will include CopyToOutput="true" for that content.
