I've posted about this here, initially believing it to be a bug rather than an apparent design decision: https://social.msdn.microsoft.com/Forums/vstudio/en-US/be5b601d-1a80-40f5-8ed8-a2a833f99f40
When building universal applications that require the use of design-time custom tools (such as Razor preprocessors), the inclusion of the "Custom Tool" file property in shared projects would be a tremendous workflow improvement. At the moment, this feature is only available in executables and libraries, which can lead to ugly dependency issues when used in conjunction with shared projects.
See attached images for a comparison of the File Properties panel in a PCL project and the same panel in a shared project.
