SandboxExternalContent Property

NavigationWindow.SandboxExternalContent Property

 

Gets or sets a value that indicates whether a NavigationWindow isolates external Extensible Application Markup Language (XAML) content within a partial trust security sandbox (with default Internet zone permission set).  

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

public bool SandboxExternalContent { get; set; }

Property Value

Type: System.Boolean

true if content is isolated within a partial trust security sandbox; otherwise, false. The default is false.

Exception Condition
SecurityException

SandboxExternalContent is set when an application is executing in partial trust.

External content is XAML content that is not included with an application as either a resource file or a content file (for more information, see WPF Application Resource, Content, and Data Files).

When SandboxExternalContent is true, and the content of the NavigationWindow is an external XAML file, the content is loaded into a partial trust security sandbox that is limited to the default Internet zone permission set. Additionally, the external content is loaded into a separate process. Consequently, the external content becomes isolated and does not have access to application-scope resources, such as resource dictionaries (for more information, see ResourceDictionary).

System_CAPS_noteNote

NavigationWindow contains external content only when the Source property is set to the uniform resource identifier (URI) for an external XAML file. NavigationWindow content that is provided using the Content property is considered internal content and, subsequently, is not isolated.
