Among other things, one or more techniques and/or systems for facilitating task completion through inter-application communication and/or for registering a target application for contextually aware task execution are provided. That is, a current application may display content comprising an entity (e.g., a mapping application may display a restaurant entity). One or more actions capable of being performed on the entity may be exposed (e.g., a reserve table action). Responsive to selection of an action, one or more target applications capable of performing the action on the entity may be presented. Responsive to selection of a target application, contextual information for the entity and/or the action may be passed to the target application so that the target application may be launched in a contextually relevant state to facilitate completion of a task. For example, a dinning application may be launched to a table reservation form for the restaurant entity.
