DYNAMIC EXTENSIONS TO LEGACY APPLICATION TASKS

Methods, systems, and techniques for adding extensions to legacy tasks as part of modernizing such tasks are provided. A user can add dynamically add task extensions to an individual legacy task by configuring them, even while a task is running. Role extensions can be added to a home desktop of a role through configuration parameters. Task extensions can be made accessible to users through UI controls added as part of the modernization procedure when a legacy task data stream is received from a host computing system. Example embodiments provide a Role-Based Modernization System (“RBMS”), which uses these enhanced modernization techniques to provide role-based modernization of menu-based legacy applications.
