If required, you can extend and modify the Unity Application Block to better suit your own requirements. You can extend the Unity Application Block by doing the following:

  • Creating Lifetime Managers that control how and when the container will dispose instance of objects.
  • Using Container Extensionsto change the behavior of the container, the instance generation, and the dependency injection features.
  • Creating Container Extensionsthat provide your own custom container behaviors.
  • Creating a New Matching Rule that provides alternative techniques for selecting classes and class members to which the Unity Application Block will attach a handler pipeline.
  • Creating a New Handler that performs the task-specific processing you require for specific method invocations and property accessors.
  • Creating a New Handler Attribute that causes the application block to add built-in or custom handlers to the handler pipeline. If you create a custom handler, you may want to create a custom attribute that developers can use to apply your handler by adding the attribute directly to classes or class members within the source code of an application.
