Define the namespace “Program11_3”.

Define a class “Program”.

Define a constructor for the class.

Define required functions to run “Form1”.

Form1.cs:

Include the required libraries.

Define namespace “Program11_3”.

Define a class “Form1”.

In Form1_Load() method,

Create an object for TeamLeader derived class.

Assign the fields value for “ProductionWorker” base class for “TeamLeader” class which is derived from base class “Employee” using “teamLeader1” object of “TeamLeader” derived class.

Display the retrieved fields into label box.

Close the application.

Employee.cs:

Include the required libraries.

Define namespace “Program11_3”.

Define a base class “Employee”.

Declare the required fields.

Define the parameterless constructor to initialize the required fields.

Define Name and Number property to use get and set methods.

ProductionWorker.cs:

Include the required libraries.

Define namespace “Program11_3”.

Define a derived class “ProductionWorker” which is derived from base class “Employee”.

Declare the required fields.

Define the parameterless constructor to initialize the required fields.

Define Shift Number and hourly rate property to use get and set methods.

TeamLeader.cs:

Include the required libraries.

Define namespace “Program11_3”.

Define a derived class “TeamLeader” which is derived from base class “ProductionWorker”. But this “ProductionWorker” class is derived from base class “Employee”.

Declare the required fields.

Define the parameterless constructor to initialize the required fields.

Define bonus, required training hour, and attended training hour property to use get and set methods.
