In this series of 4 tutorials, y'all'll build a math quiz. The quiz contains 4 random math issues that a quiz taker tries to reply within a specified time.

The Visual Studio integrated development environment (IDE) provides the tools that you need to create the app. To learn more about this IDE, see Welcome to the Visual Studio IDE.

In this beginning tutorial, you learn how to:

• Create a Visual Studio project that uses Windows Forms.
• Add labels, a button, and other controls to a form.
• Set properties for the controls.
• Save and run your project.

Prerequisites

Y'all need Visual Studio to complete this tutorial. Visit the Visual Studio downloads page for a costless version.

Create your Windows Forms project

When you create a math quiz, the first step is to create a Windows Forms App project.

1. Open Visual Studio.

2. On the card bar, select File > New > Project.

3. On the left side of the New Project dialog box, select either Visual C# or Visual Bones, and then select Windows Desktop.

4. In the project templates list, select Windows Forms App (.Internet Framework). Name the new form MathQuiz, and then select OK.
