A common mistake in programming event handlers is connecting the event handler to an object that has been declared with a scope too limited for the purpose of handling the event. The object must have a life that spans not just over the function that connects the callback method as an event...
COM has its way of handling events and .NET has its and, through the magic of COM interop, we can tie these two disparate programming models together. This means that we can have a COM event source and a .NET event handler. However, the code we need to write to handle events in C#...
Layout dependency is only an issue for COM programming. In native and managed event handling, the signatures (return type, calling convention, and arguments) of the handlers must match their events, but the handler names do not have to match their events. ...

A traditional synchronous event handler in C# has the following syntax: voidMyEventHandler(objectsender,EventArgse){// TODO: handle the event} But if we need one to run asynchronously, it will look like this: asyncvoidMyEventHandler(objectsender,EventArgse){// TODO: handle the event, running...
The event model in .NET is based on having an event delegate that connects an event with its handler. To raise an event, two elements are needed: A delegate that refers to a method that provides the response to the event. Optionally, a class that holds the event data, if the event pr...
