When I switched over the C# compiler team, I had hoped that I would be able to give some insight into how the design team works, what decisions we make, etc. Language design is a very esoteric field, and there's not a lot written about it (though “Design and evolution of C++“ is a pretty good read). I had hoped that I would be able to do this with concrete examples, as that makes it much easier.

I've been watching for candidate topics to write about, but haven't yet come up with any good ones. One of the problems is that features have a tendency to morph in design (and in whether they'll make it into Whidbey) as time goes by, and it would be bad for me to say, “we're talking about doing“ and then have us decide it wasn't a good idea. Or, for us to decide that doesn't fit into our schedule, or it would break existing code, or any of the other reasons that might cause us to pull a feature. We're generally not comfortable re

Architecture

• Use Onion architecture

  • Dependencies go inwards. That is, the Core domain doesn't know about outside layers

• Use pipeline model to implement workflows/use-cases/stories

  • Business logic makes decisions
  • IO does storage with minimal logic
  • Keep Business logic and IO separate

• Keep IO at edges

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
