山东泰迪计算机软件工程师培训学校

2. What?
Fundamentally change the way you think about
coordinating and orchestrating asynchronous
and event-based programming

3. Dualize Enumerable Collections
Interface IEnumerable<out T>
{
//void->enumerator
IEnumerator<T> GetEnumerator();
}
Interface IObservable<out T>
{
//observer->void
Subscript(IObserver<T> o)
}

4. IEnumerable & IEnumerator are prototypical
interfaces for interactive collections and
interactive programs.
IObservable & IObserver are prototypical
interfaces for observable collections and
reactive,asynchronous & event-based programs.

5. LINQ to Observable
If you are writing LINQ or declarative code in an
interactive program……
You already know how to use it!!!
