I have a c# library whose target framework is Mono/.NET 4.5. I can not reference it from another portable library whose target framework contains .NET 4.5 or later.

Project attached.

A PCL project can only reference projects/libraries that target the same PCL profile. However, a PCL library/project can *be referenced* from projects that target any of the frameworks the PCL profile supports.

The reason why: suppose you had a PCL library that used a profile that supported .NET 4.5 and Windows Phone 8. That means you could reference the PCL project from a Windows Phone 8 project. It wouldn't make sense for the PCL project to be able to reference a .NET 4.5 library, because then a Windows phone project could indirectly reference a .NET 4.5 library, which would not work.
