Screen Shot of the IJavaPeerable syntax error

Xamarin syntax highlighting shows the error "Error: the type 'IJavaPeerable' is required here and is unavailable. You must add a reference to the assembly 'Java.Interop, Version=, Culture=neutral,PublicKeyToken=84e04ff9cfb79065'.'

The 'IJavaPeerable' error appears on any F# class type that inherits a Java base class. But, it only appears in the syntax highlighting. The code will compile and run. I've yet to see any issues arise from this error at runtime, or compile time.
