Help me pick a Dependency Injection framework for .Net

Question

Which C#/.NET Dependency Injection frameworks are worth looking into?

Yes I know this question has been asked many times, but the various frameworks keep evolving, so I would like a fresh answer on the subject.

A few thoughts about the framework, they are not necessary black or white, but rather my preferences.

Things I like:

• Convention based registrations
• Constructor injection
• Can also target Silverlight
• Small footprint
• One assembly
• Fast

Thing I don't like:

• Xml
• Custom attributes
• Service locator pattern

Things I don't think about:

• Linq
• Opensource

Answer 1

Sounds like you might want to try NInject.

It has a definite focus on being easy to use with little configuration overhead (no bulky XML config files, etc). It even comes with a nice, shiny, fluent interface to make things understandable.

Answer 2

autofac

Ninject

Answer 3

When you're not familiar yet with any of the big DI frameworks, you might consider the very easy SimpleServiceLocator (shameless plug). Let's compare it to your check list:

• Constructor injection, check!
• Can also target Silverlight, check!
• Small footprint, check!
• One assembly, nope 2. It needs the Common Service Locator.
• Fast, double check!
• No Xml, check! Only code based configuration is supported.
• No Custom attributes, check! It is completely attribute free.
• No Service locator pattern, check. Despite its name, you can do DI with it (just look at the examples on the site).
• Open source, check! MIT License.

The idea behind the Simple Service Locator is:

to provide .NET application developers with a inversion of control (IoC) framework that is truly easy to use, while allowing developers to replace it with a more feature-rich IoC framework when needed.

The Simple Service Locator is an implementation of the Common Service Locator library. The Common Service Locator is a shared interface for inversion of control and dependency injection which application and framework developers can reference.
