Classes Used in .NET Framework User Operations (Visual Basic)
The IIdentity and IPrincipal interfaces form the basis of the .NET Framework user-authentication system. You can use implementations of these interfaces that the .NET Framework provides, or you can implement these classes yourself.
Basic Classes Used for User Operations
Most of the classes that support user operations are located in the System.Security.Principal namespace. For a more comprehensive listing, consult the .NET Framework documentation.
The following classes implement the IIdentity interface, which defines the basic functionality of an identity object.
