NuGet Warning NU5108

The transform file 'other\code.pp' is outside the 'content' folder and hence will not be transformed during installation of this package. Move it into the 'content' folder.

Issue

An .pp or a .transform file was detected in a folder other than content folder.

Solution

Please place the .pp or a .transform file under the content folder for it to be compatible with NuGet tooling.
