You are designing a new feature for an existing Windows Forms application by using Microsoft .NET Framework 4.
The application contains multiple forms that are loaded into a parent Multiple Document Interface (MDI) form.
Your company policy does not allow the use of third-party controls.
You need to ensure that the new feature meets the following requirements:
- It provides a three-dimensional scale model.
- It allows users to change the colors of the model and communicates the color selections back to the application.
- It allows the model to scale, based on the user’s client computer display resolution.
- It is a child form in the MDI application.
What should you do?
A. – Design the new feature in the existing Windows Forms application as a Windows form.
- Add the form as a child form to the MDI window.
B. – Design the new feature in a new application by using Windows Presentation Foundation (WPF).
- Invoke the new WPF application from the existing Windows Forms application.
C. – Design the new feature in a new Windows Presentation Foundation (WPF) application.
- Host the existing application inside the new WPF application by using the Windows Forms Host class.
D. – Design the new feature by using a Windows Presentation Foundation (WPF) user control.
- Use the Element Host class to host the WPF user control in the existing Windows Forms application.
