The ApplicationDirectory evidence class represents the root installation directory of an application. A URL representing the application installation path is passed as a System.String to the ApplicationDirectory constructor, and is accessible through the Directory property.

The ApplicationDirectoryMembershipCondition class uses ApplicationDirectory evidence during policy resolution to evaluate whether an assembly or application domain qualifies for membership of a CodeGroup.
