System.Net.NetworkInformation Namespace

Microsoft Silverlight will reach end of support after October 2021. Learn more.

The System.Net.NetworkInformation namespace provides access to information on network availability and notification of address changes for the local computer.

This namespace is used to enable basic detection of changes in network state, such as address or interface state changes. Applications can keep track of when to get application data and assets from the network or from a local cache and can decide if they should make remote network calls. This helps enable offline Silverlight applications.
