For this activity, you will create a Word Occurrence Calculator. Create a Windows Forms Application that contains a multi-line TextBox control (Input), a Button control (Calculate), and a Label control (Result). Your application will allow the user to enter text into the multi-line TextBox, and will calculate the number of occurrences of each unique word in the TextBox. Each unique word along with its number of occurrences will be displayed on a single line in the Result label.
