Update suggestion for how to include PDBs in package (#246)
Update suggestion for how to include PDBs in package (#246)

This is the currently recommended way to include any content in the package that is TFM-specific.
Any targets added to the `TargetsForTfmSpecificContentInPackage` property will be executed once for
each TFM in the project, with `$(TargetFramework)` property set to the correct value.
