DunDDD F# for fun and games slides and demos

Relevant slides and demos from my F# for fun and games presentation yesterday at DunDDD.


REPL demo

Platformer demo (The C# version isn’t open source and I’m not sure whether it will be released openly)

The other demos were very simple scripts which are mostly covered in the slides themselves.

Unable to copy file when compiling an F# project

This is just going to be a really quick post on how to solve this problem I get occasionally and it fits in with what was made in the post on using MonoGame with F# interactive. When you try and compile an F# project, you may get a series of warnings telling you that the file copy operation timed out. Then after 10 of these warnings you get an error and a build failure. This error probably means that the library you are trying to use was referenced in the F# interactive window by using the #r directive.


To solve it you have to simply reset your interactive session by right clicking within the F# interactive window and selecting reset interactive session. Unfortunately there doesn’t appear to be a way of dynamically unloading any assemblies and so you will end up losing your current interactive session.
