You are updating a Windows application by using the .NET Framework 3.5.
You are required to upgrade the UI for the application from Windows Forms to Windows Presentation
Foundation (WPF).
The new version of the application will include new UI components.
You need to ensure that an interim release of the application will support the new UI components within
Windows Forms. You want to achieve this goal by using minimum development effort.
What should you do?

A.
Develop WPF controls that can be hosted in ElementHost controls.

B.
Develop WPF controls that can be hosted in WindowsFormsHost controls.

C.
Develop WPF pages that are hosted in XAML Browser applications. Host the application by using
WebBrowser controls.

D.
Develop WPF controls that include COM callable wrappers. Access the controls by using runtime
callable wrappers.
