Description

[Note: The types that derive from System.Security.Permissions.CodeAccessSecurityAttribute are used to secure access to resources or securable operations. The security information declared by a security attribute is stored in the metadata of the attribute target, and is accessed by the system at runtime. Security attributes are used for declarative security only. Use the corresponding permission class derived from System.Security.CodeAccessPermission for imperative security.]
