# How to: Determine If a Page is Browser Hosted
This example demonstrates how to determine if a <xref:System.Windows.Controls.Page> is hosted in a browser.  
  
## Example  
 A <xref:System.Windows.Controls.Page> can be host agnostic and, consequently, can be loaded into several different types of hosts, including a <xref:System.Windows.Controls.Frame>, a <xref:System.Windows.Navigation.NavigationWindow>, or a browser. This can happen when you have a library assembly that contains one or more pages, and which is referenced by multiple standalone and browsable (XAML browser application (XBAP)) host applications.  
  
 The following example demonstrates how to use <xref:System.Windows.Interop.BrowserInteropHelper.IsBrowserHosted%2A?displayProperty=nameWithType> to determine if a <xref:System.Windows.Controls.Page> is hosted in a browser.
