Jon Skeet Creates an IoC Container

This is an outtake of Tekpub's C# Design Strategies production. During the recording of Episode 4 (Inversion of Control) we asked Jon to "lead people along and show them the need" for using Inversion of Control with Dependency Injection. We expected a rough, hard-coded factory-style of thing, but no, Jon built a small, functional IoC container from scratch. We decided to include it here because it's fascinating to watch and... he's Skeet!

I note with embarrassment how Rob calls it absolutely correctly at 13:57: "I guess Instance is a property, right?"

Doh, doh, doh.

Jon Skeet. The man, the myth, the legend!

[ValiRossi]

Not at all surprised Jon could do this. Amazing.

Awesome video, learning from this course alone, made whole year Tekpub subscription worthwhile.

I dont follow 80% of the things he is talking about but it is mad impressive to see a brilliant man at work

My takeaway from this is that Skeet was successful because he was able to define the problem narrowly, define and consume the interfaces in question up front, and define the lynchpin (the dictionary data structure mapping strings to instances). Even when he encountered problems he never once considered changing the data structure or the interface/client call; he knew to work around these constraints to achieve his goal.

Hat-tipping to mr Skeet! Amazed... that's all.
Thank you

I made one using a static class. Maybe I'll make another one more like this :-)

i feel bad about my programming skills. Awesome video Jon

[bubbassauro]

Witchcraft! I feel so bad as a programmer now I want to throw my computer out of the window and hide under the bed.

Kidding aside, that was impressive. Great video, thanks! :)

No deliberate skinning - that's just what the VS11 beta looks like.

[rolandemmet]

Is it bad that the only words I understand is public and private, and a few others more "daily-familiar" words? I don't know anything about this, but for some reason, am amazed. Can anyone explained what this is all for for a more "ordinary" human-being?

[martinpratley]

Cool programming skills even though i didnt understand any of it.

[Kangoo]
