FSX Structure

I use this basic template when writing .fsx files that I might want to compile. It adjusts the difference in command line/entrypoint handling between a script and a compiled assembly. This example shows the details for a WPF script — replace the #r's and/or remove the STAThread for a WinForms or Console script.
