ApplicationId Class

Contains information used to uniquely identify a manifest-based application. This class cannot be inherited.

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

Public NotInheritable Class ApplicationId
'Usage
Dim instance As ApplicationId

/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */

An application identity consists of the publisher's public key, the application name, the target processor architecture, the application culture, and the application version. The application identity properties values correspond to information contained in the application manifest. For more information about manifest-based applications, see ClickOnce Deployment Overview.

ApplicationId is used by the ApplicationSecurityInfo class to identify a manifest-based application.

The following code example displays the ApplicationId properties by obtaining the ApplicationId from an ApplicationSecurityInfo instance created using the ActivationContext for the currently executing manifest-based application.
