Fun with Func<T,TResult> Delegates, Events and Async Operations

Delegates are powerful for event handling, highly useful in LINQ and a core requirement for async operations. Func<T> makes using delegate based logic a lot easier by providing a generic implemenation that in many cases allows you to skip creation of a separate delegate and instead just point at the Func<T> definition which can be a big timesaver and a nice way to remove delegate defintions from your namespaces.
