- Download Rx Framework from here.
- Install it.
- Create New Windows Forms project (you can choose WPF, Silverlight, WP7). I used WinForms in my example.
- Add TextBox and ListBox to it as you see below.
5. Add System.Reactive reference to your project (see image below).
6. Create any dummy data (you can use any repository you want) and just to make things fast
7. Add this chunk of code.
When TextChanged raised the subscribed code will be executed Asynchronously.
That’s it. As simple as that.
