ILSpyMono is a demo project for compiling ILSpy as a CLI app for Mono framework.
Website: https://github.com/andreif/ILSpyMono
You can build this project from my ILSpy fork which includes it as git submodule. After cloning the ILSpy fork, make sure Mono.Cecil* projects have proper configuration (e.g. net_4_0_Debug) referenced in the solution settings.
I have not found a good way to use UpdateAssemblyInfo.exe so had to remove it from decompiler project. I guess one could have changed it to mono path/to/UpdateAssemblyInfo.exe... etc.
This is my first C# project ever and it was made quick-n-dirty, so you may not like the code. If you see how one can make it better, please submit an Issue or a Pull Request.
