I’m still on my journey with exploring F# but I want to look at something with the .Net Core platform itself, so this will apply to both C# and F#. Ahead-Of-Time (AOT) compilation isn’t a new concept. Languages like C and C++ need to be compiled before (or ahead of) execution time. The JVM and CLR took a different approach, creating “virtual machines” or runtimes that could run your code, giving us the promise of “write once, run anywhere” or anywhere that has a virtual machine at least.
