.NET Remoting is an API designed to manage inter-process communication (IPC), where data is swapped among multiple threads in various processes. It was released in tandem with .NET Framework 1.0 back in 2002. Microsoft downgraded .NET Remoting to legacy technology status when it released version 3.0 of .NET Framework and has since recommended developers use WCF (Windows Communications Foundation) to build distributed applications. Unlike WCF, which can be used by different languages and platforms, .NET Remoting works only in a homogenous .NET environment. Moreover, .NET Remoting cannot utilize modern protocols like SOAP or MSMQ (Microsoft Message Queuing), among other limitations. Microsoft maintains information about .NET Remoting for backward compatibility with existing applications.
