Why would you use .NET Remoting over WCF?
I understand that WCF has its distinct advantages, but what advantages would .NET Remoting offer you over the more modern WCF technology?
WCF provides the ability to essentially do exactly what .NET Remoting does through the choice of binding you use when configuring your WCF service.
WCF abstracts the idea of a service from the transport technology that is used to implement that service. You can define a WCF service and then change the transport technology used to provide that service through configuration, one of these being net/tcp which is essentially the technology .NET Remoting uses.
WCF is more of a replacement for .NET Remoting than an alternative.
