Eventdrivenprogramming can be implemented with so-called procedural languages, so perhaps we need to be careful about making it appear as if. In this lesson we demonstrate how events are utilized in the net framework class library specific to wpf and aspnet web forms applications in these examples, we see how c# is generated by the ide t. We describe the design and implementation of p, a domain-specific language to write asynchronous event driven code p allows the programmer to specify the system as a collection of interacting state machines, which communicate with each other using events p unifies modeling and programming into one.
