Quick test snippet for finding out if two libraries expose the same public API
View 00_README.md

This is a short test of comparing the public API in two .NET binaries. There isn't any special comparison being done beyond determining whether or not the public APIs match perfectly.

To determine whether or not the two APIs match, build the .cs files like so:

csc /out:Lib1.dll /target:library 10_Lib1.cs
csc /out:Lib2.dll /target:library 20_Lib2.cs

Decompiled record update syntax to see what the IL is doing
View 1_README.md

Original code is in Record updates.fs, the IL output for the type is in type.il, and the IL output for the function is in func.il. Also included ILSpy's interpretation of the function into C# code in func.cs.

# To use this script, go into your GitHub account settings, go into the
# Applications section, and then under `Personal access tokens` click
# `Generate new token`. Name the token whatever you want, give it access
# to the `repo` and `public_repo` scopes (`user` and `gist` are also
# selected by default, but you don't need them for this).

# Take the generated token and store it in your personal .gitconfig
