Mono source code walkthrough / tutorial

Question

I checked out the Mono source code, and searched all files for some of my favorite .NET classes with no results. I'm pretty lost and I want to know:

1. In which language Mono is written?
2. Where are, in all those folders, the source files with the equivalent .NET classes implementations?
3. It's easier to build it in Windows or Linux?

Answer 1

1. The runtime, JIT and AOT is written in C, most of the other tools in C#. Even the C# compiler is written in C#.
2. /trunk/mcs/class/ That is, /mcs/class/{assembly}/{namespace}/{class}.cs for code files.
3. Currently definitely Linux, as this was were they started to develop for, this as full build support. On windows cygwin is required, I don't know if the Visual Studio project files are completed yet.
