Which .NET Dependency Injection frameworks are worth looking into?

Hi,

As a new kid in the C#/.NET block just moved in from Java neighbourhood, I am looking for options in Dependency Injection/IoC frameworks for .NET/C#.

From Scott Hanselman's blog post few years ago I got a fairly long list of DI frameworks, but there was really not enough information to go with beyond the list itself (plus a license and a version number) to make any semi-intelligent choice. Nor have I developed a ghestalt of the relative popularity (and thus the community support available) for any of these. And the list itself dates from 2008, which makes it a bit outdated, so I would like to ask kindly SO community for help on this matter.

Please list (or vote for) your favourite DI framework, adding a link to framework official website and please be so kind as to provide some reasoning for helping me and others developers like me to make a choice.

A code sample snippets for declaring and injecting dependencies would be of great help as well.

NB: Please restrict yourselves to one entry per response please, to keep it simple and objective.

    This surely have been discussed here at SO previously: http://stackoverflow.com/questions/21288/which-net-dependency-injection-frameworks-are-worth-looking-into and http://stackoverflow.com/questions/4581791/how-do-the-major-c-di-ioc-frameworks-compare – Peter Lillevold Feb 28 '11 at 09:51

    `Please restrict yourselves to one entry per response please, to keep it simple and objective` How can it be objective when everyone vote on their favorite container? – jgauffin Feb 28 '11 at 11:21
  • @jgauffin: by "objective" I meant that the results of such "voting" would very likely reflect relative popularity and mindshare of projects in question... Bun nevermind, as this question was closed as duplicate.... – Roland Tepp Feb 28 '11 at 15:10
  • Yes, but everyone would still vote on their favorite framework. There are no correct answers, just subjective ones. – jgauffin Feb 28 '11 at 17:01
  • @jgauffin it's simple statistics - given enough subjective opinions, trends start to emerge that are as objective as such can be. – Roland Tepp Mar 01 '11 at 09:18

I have used Ninject before and got on well with it. There are code samples on the front page of the website.

Edit: Ninject also supports MVC

Of those I have tried, I like Unity best by far. Easy to use, and feature rich. A note is that it's not supported if you are developing for Windows Phone 7.

Of the list I've tried Unity, StructureMap and Autofac.

I perfer StructureMap, I think it's the most straightforward and easiest to use. (didn't spend much time with Autofac tho since was just messing in my own time)

You could also use MEF, but be aware that MEF is not only for this purpose. Mostly MEF is a little oversized for normal DI scenarios, but very usefull if you intent to develop a extendible app.
