Programming 2 in C#

You have been asked to help out a team working on a new software package for a client. The
package is designed to help client keep track of appointments at their business. The functionality is
similar to the calendar functionality in Microsoft Outlook.

Unfortunately, one of the team has just
left the company without completing their work and you have been asked to produce the parts of
the application that have not yet been produced. You have been given a specification to work to.
The final user interface will look something like the following:
The main user interface has been written. Your tasks are as follows:

Task 1: Write the classes that manage and store entries in the calendar.
Task 2: Write the Windows forms that users of the application will use to enter details of
new entries in the calendar and edit existing entries.
Task3: Integrate your code into the other parts of the application that have already been
written and add the ability to create new entries in the calendar, edit existing ones
and delete entries.
