How Can I Detect Design Mode in WPF, Silverlight, WP7, and Windows Store Apps?

Checking Design Mode in WPF: Exploring Various Approaches

Recognizing whether WPF is executing in design mode is essential for certain scenarios, such as displaying mock data in design tools. To address this need, various methods exist, including relying on global variables or utilizing dependency property checks.

One approach involves employing the GetIsInDesignMode method on a dependency object, which returns a boolean indicating whether the associated element is in design mode. However, in Silverlight or WP7, the IsInDesignTool property should be used instead, as GetIsInDesignMode may produce unreliable results.

For Windows Store applications, the DesignModeEnabled property of the Windows.ApplicationModel.DesignMode class provides the required information. The following code demonstrates its usage:

Windows.ApplicationModel.DesignMode.DesignModeEnabled

This property returns a boolean that is true when the application is in design mode and false when it's running as a normal application. By utilizing such properties, developers can seamlessly differentiate between design mode and runtime environments, enabling the adaptation of application behavior accordingly.
