Polyphonic C#

Distributed programming is one of most important technology in enterprise application. Therefore, many development tool, such as .NET also supports asynchronous method call.

Indeed, .NET already has a widely-used set of library classes which allow any method to be invoked asynchronously (though note that in this standard pattern it is the caller who decides to invoke a method asynchronously, whereas in Polyphonic C# it is the callee (defining) side which declares a particular method to be asynchronous). The significant innovation in Polyphonic C# is the way in which method bodies are defined.
