Extending and Modifying Unity

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

Creating Lifetime Managers that control how and when the container will dispose of instances of objects it resolves.
Creating and Using Container Extensions that can change the behavior of the container, the instance generation mechanism, and the dependency injection and interception features.
Creating Policy Injection Matching Rules that provides alternative techniques for selecting classes and class members to which Unity will attach a handler pipeline.
Creating Interception Policy Injection Call Handlers that perform the task-specific processing you require for method invocations and property accessors.
Creating Interception Handler Attributes that cause Unity to add built-in or custom call handlers to the handler pipeline. If you create a custom handler, you may also 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.
Creating Interception Behaviors that describe what to do when an object is intercepted.
