The ApplicationDirectoryMembershipCondition membership condition class uses the value of both ApplicationDirectory and Url evidence to determine if an assembly or application domain qualifies for membership of a CodeGroup. The Check( ) method returns true if the specified Evidence collection contains both Url and ApplicationDirectory evidence, and the Url.Value property represents a location that is a child of the ApplicationDirectory.Directory property.
