Good IOC Frameworks to use with asp.net mvc?

Question

Hi

I am wondering what good simple IoC frameworks are there for asp.net mvc? that have good documentation and are just easy to get up and going.

Thanks

Answer 1

I've used Autofac and have been very happy with it.

Configuration is mostly done in code so you get compile time checking for your mappings as opposed to programming in XML and hoping for the best. It also supports XML overrides though so if you absolutely need to leave something to be configured at run/deploy time it's possible.

The Contrib (not sure what to call it?) portion provides integrations for NHibernate, Moq, etc. The creator of the project worked at Microsoft for a year on the MEF team so there's some MEF integration as well.

The documentation section of the site is pretty good (though if you don't find what you need there, it probably doesn't exist...yet). On the up side the author is on SO so if you have questions and tag the appropriately you could probably get quality answers.

2. NHibernate and WPF: The GuyWire - Although it's written in the context of WPF, the same concept would apply to a webapp.

Answer 2

S#arp Architecture is admittedly a lot more than just IoC. It uses Castle/Windsor for IoC.

I would recommend it as a larger set of best practices for the framework of your MVC application.

Answer 3

I have used Unity and it is good.

Answer 4

I use Windsor Castle, other people say that Structure Map is really good, but basically they all do the job
