ActivationContext Class

Identifies the activation context for the current application. This class cannot be inherited.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
<SerializableAttribute> _
<ComVisibleAttribute(False)> _
Public NotInheritable Class ActivationContext _
	Implements IDisposable, ISerializable
'Usage
Dim instance As ActivationContext

The ActivationContext class contains an ApplicationIdentity and provides internal-only access to the application manifest. The activation context is used during manifest-based activation to set up the domain policy and provide an application-based security model. For more information, see the ApplicationSecurityManager class.

The following code example demonstrates the use of an ActivationContext object to obtain the ApplicationIdentity for a manifest-based application. For correct results, execute this code example as a manifest-based application.
