Changing requirements, introducing different data format, extending applications with new features. All those things requires us (developers) to go to code, do changes, add API versioning system (to be backward compatible), add configuration for turning on/off new features, compile application, and at the end release new application (what itself may be complex process). It’s often lot of work required for every, even very small, change.
In this post I’ll present way to add new features to our F# application - dynamically, on runtime, without any recompiling and redeployment of application. What’s more extensions will be also defined using F#… in fact they will be simple F# script files.
