Assembly: System (in System.dll)
The existing System::Uri class has been extended to provide support for International Resource Identifiers (IRI) and Internationalized Domain Names. Current users will not see any change from the .NET Framework 2.0 behavior unless they specifically enable IRI and IDN. This ensures application compatibility with prior versions of the .NET Framework.
IRI processing must be enabled for IDN processing to be possible. If IRI processing is disabled, then IDN processing will be set to the default setting where the .NET Framework 2.0 behavior is used for compatibility and IDN names are not used.
The Internationalized Domain Name (IDN) attribute only controls IDN processing. All other IRI processing (character normalization, for example) is performed by default.
For more information on IRI support, see the Remarks section for the System::Uri class.
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
