System.Security namespaces

The System.Security and System.Security.Principal namespaces contain classes that represent the .NET Framework security system and permissions.

This topic displays the types in the System.Security and System.Security.Principal namespaces that are included in the .NET for Windows Store apps. Note that the .NET for Windows Store apps does not include all the members of each type. For information about individual types, see the linked topics. The documentation for a type indicates which members are included in the .NET for Windows Store apps.
