2.Charles is assigned the task to develop a Windows Store app named MyToDo, which allows users to maintain a to-do list. It allows the user to add or delete the tasks to be performed. For this, the controls are available on the App bar of the app. The form for accepting the details from the user should be similar to the one shown in the following figure.

should be similar to the one shown in the following figure.
The Expected Interface of the App



When the user adds tasks, they should be displayed in the form as shown in the following figure.
The Expected Interface of the App after Adding Tasks
To delete an existing task, the user needs to select the task, and then right-click the blank area of
the app. The user can delete the selected task by clicking the Remove button that appears on the
App bar, as shown in the following figure.
The Remove Button on the App Bar
Charles has added the required controls to allow addition of tasks in the app. However, when a
user adds a task, he/she is able to see only the name of the task. Further, when a user clicks the
Remove button available on the App bar, the records are not deleted.
Help Charles to identify the reason and the solution to the problem.
