BrowserInteropHelper.IsBrowserHosted Property

Gets a value that specifies whether the current Windows Presentation Foundation (WPF) application is browser hosted.

Namespace:  System.Windows.Interop
Assembly:  PresentationFramework (in PresentationFramework.dll)

public static bool IsBrowserHosted { get; }

Property Value

Type: System.Boolean
true if the application is browser hosted; otherwise, false.

A Page can be host agnostic and, consequently, can be loaded into several different types of hosts, including a Frame, a 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 BrowserInteropHelper.IsBrowserHosted to determine if a Page is hosted in a browser.

// Detect if browser hosted 
if (BrowserInteropHelper.IsBrowserHosted) 
    // Note: can only inspect BrowserInteropHelper.Source property if page is browser-hosted. 
    this.dataTextBlock.Text = "Is Browser Hosted: " + BrowserInteropHelper.Source.ToString();
    this.dataTextBlock.Text = "Is not browser hosted";
