The Property instances that are returned by these methods are no longer automatically registered as inputs or outputs of the task.
The Property instances need to be declared as inputs or outputs in the usual ways, such as attaching annotations such as `@OutputFile` or using the runtime API to register the property.

For example, you could previously use the following syntax and have both outputFile instances registered as declared outputs:

====

// Calls Run()
// Verifies there is one attach call and no detach calls.
// Deletes the node/volume/pod tuple from desiredStateOfWorld which succeeded in attaching
// Verifies there are two attach call and one detach call.
func Test_Run_OneVolumeAttachAndDetachMultipleNodesWithReadWriteOnce(t *testing.T) {
	// Arrange

* Kubernetes v1.3 introduces a new Attach/Detach Controller. This controller manages attaching and detaching of volumes on-behalf of nodes.  ([#26351](https://github.com/kubernetes/kubernetes/pull/26351), [@saad-ali](https://github.com/saad-ali))

====

Using the runtime API like this is a little like using `doLast()` and `doFirst()` to attach extra actions to a task, except in this case we’re attaching information about inputs and outputs.

WARNING: If the task type is already using the incremental build annotations, registering inputs or outputs with the same property names will result in an error.
