This is almost so convenient. I can include the FlightQuest.dll in my project and that lets me call the F# functions in "Serialization.fs", and most of the other files, right from my C# code.

\n

But I can't seem to call "loadMaps()" or any of the other helpful-looking functions in "Program.fs", so I need to translate them into C#. I confess, I'm having a lot of trouble with this translation. (In my defense, even the Xamarin debugger declares that some of the variables being passed around are "in a zombie state.") In the long run, I'm hopeful I can make this work.

\n

But right now, I wish I had just two more functions that I could call from my C# code. The first would simply load everything, exactly as runSimulation.exe does on startup. The second would take one flight and one path (in some nice format like a string or an array please) and return the score after simulating just that one path for just that one flight.

\n

I actually have this equivalent functionality using "System.Diagnostics.Process ()" to interact with runSimulation.exe. It's fine for testing, but involves too much file IO for me to optimize 15K flights this way.

Simulator.simulateFlight does exactly this.  Take a look at simulateFlights for how it's being used.

Yes, it would be great to call simulateFlight(), if only I could figure out what to pass to it (and it's not something "nice") and how to get the airport and other data read in first.

\n

I'm not finding fault here. I'm asking if there's a way around this obstacle. It's great that we can call these functions from another language. Could you please fix it so we don't have to translate a good chunk of optimized-to-run-in-parallel F# code to do so?

You don't need to translate the code - you just need it to be in a library.  Create a new F# library, add a reference to FlightQuest, copy over the desired methods, make modifications to fit your needs, and then reference this project from your C# project.
