Has anyone experienced problems when NuGet pack command doesn't pick up the /App_Start or /content/App_Start folders where we put our .pp files for use with the WebActivator package?
I have to open the package with Package Explorer and then manually add the desired folders and files, which is troublesome.
As dfowler suggests, it only includes files that are in the project. In the project, try clicking View All Files, and then include the relevant .pp file, with a build action of 'Content'.
As an alternative, you can explicitly list those files in the nuspec file and they will be included.
