Template which reproduces the error

## Steps to reproduce ##
1. Download the attachment, or create a new F# GTK# template in XS/VSfM: New Solution -> Other -> .NET -> Gtk# 2.0 Project -> F#.
2. Attempt to build, the following error should manifest:

> error FS0433: A function labeled with the 'EntryPointAttribute' attribute must be the last declaration in the last file in the compilation sequence.
This template (and previously existing projects created from this template) are building successfully against the command line xbuild and msbuild tools which ship with mono 4.8.0. This error is new in mono 2017-02.
