IoC Containers - Which is best? (.Net)

Question

I'd like to get a feel for what people are using for IoC containers. I've read some good things about Castle Windsor, but I know a lot of people use StructureMap, Unity, Ninject, etc.

What are some of the differences amongst those mentioned (and any I neglected). Strengths? Weaknesses? Better fit (like StructureMap is great for ABC but not so good for XYZ)?

Answer 1

"Best" will always be subjective.

That said, I favor Castle Windsor because its XML is simpler. I've only tried Windsor and Spring.NET, by the way, so I couldn't say much about the others.

Answer 2

I like StructureMap. The latest version allows you to declare inline too without having to resort to XML configuration files.

Answer 3

I like much Ninject... is simple, easy to use, it has such kind of fluid notation to declare bindings between classes and interfaces and supports contextual binding. Awesome.
