.NET CIL interpreter in F#

#dotnet #functional

I've prepared compact .NET CIL interpreter called Fint in pure F# for NskDotNet Meetup #6.

It can run C# programs with the following features at this point:

all control flow statements (if, for, switch, etc)
arithmetic operations including bitwise one
boolean algebra operators
string concatenation
static function calls
Console.WriteLine calls

It can be easily extended with other features.

Some code in this project is just ported from PageFX project I wrote about recently.

It would be nice to try porting Fint to JavaScript using Fable and run .NET binary code right in a browser.
Later we can try to port Roslyn C# compiler to WASM with Blazor compiler and build online tutorial that:

compiles small C# program to .NET PE file in browser
runs .NET PE file in browser
shows CIL code for given method
provides debugging experience of CIL instruction set

This could be a great web resource to help learning .NET code at low-level.

If you like Fint repo please stargaze it on github.

Here is a recording of my presentation. Sorry for speaking so boring 😄
