This section highlights some of the major differences between Web Services and .NET's Remoting technology. Web Services are interoperable, i.e., they enable cross platform integration. This means they can run in heterogeneous environments. They can be used for exchange of data independent of platform or language. In contrast, .NET Remoting can only run in homogenous environments. It requires that both the Server and the Client should be .NET and, hence, have the .NET Framework installed in them. However, Web Services can be invoked only over HTTP while Remoting can be used across any protocol. Web Services are stateless while we can have support for state management using Remoting.
