TInjector

A simple .NET IoC container with only the features needed for correctly-designed applications.

NOTE: This is very much still under development. I have already re-written the whole thing several times. I'm not certain I'll ever be happy with its performance or design. It is largely just a platform for me to experiment with and basically deep dive into DI and IOC.

Design Decisions

• Only support features necessary for properly designed apps
  • No extensible scopes (prevent messy scope-dependant code)
  • Once a root (container/kernel/etc.) is created lock it against further modification
  • Do not support automatic registration of concrete classes (you should always wrap it in an interface so you can test things that use it)
• Fully strongly typed fluent configuration interface
• No reflection in the core lib
  • typeof(T) is allowed to get Type instances to be used as dictionary keys, but no properties or methods on Type instances may be called.
• High concurrency (lock as little as possible)
• Support heavy automation (automatic registration wherever reasonable)
  • In some cases this might conflict with not using reflection in the core lib. In such cases the reflection is to be moved to a companion library or the feature that needs it is to be removed all together.
• Testability (unit test all the code, create an api that allows extensive unit testing of anything using it)
• Simplicity (of the code, of the api, of the documentation, everywhere)
• Documented code (XML docs on all protected or public code, notes inside code on pretty much every line)
• Portability

TODO:

• Support decorators? (implements the same interface and takes the base implementation as a constructor param)
• Better method generation in TInjector.Reflection using generated IL (System.Reflection.Emit) or expression trees (System.Linq.Expressions)
