  • You can save the videos in order to watch them offline.
  • If all you want is to hear the audio, you can download the MP3!

Which version should I choose?

  • If you want to view the video on your PC, Xbox or Media Center, download the High Quality WMV file (this is the highest quality version we have available).
  • If you'd like a lower bitrate version, to reduce the download time or cost, then choose the Medium Quality WMV file.
  • If you have a Zune, WP7, iPhone, iPad, or iPod device, choose the low or medium MP4 file.
  • If you just want to hear the audio of the video, choose the MP3 file.

Async involves some new concepts. They're not difficult; just unfamiliar. Over the past year Lucian Wischik has been watching how people use async/await in C# and VB. This series distils out the three top async patterns and anti-patterns.

Tips:

  1. Async void is for top-level event-handlers only, and event-like things. Don't use it elsewhere in your code.
  2. It's crucial to distinguish CPU-bound work (should be done on threadpool) from IO-bound work (which needn't).
 If you understand the basic flow of control in an async method, then those three points all fall naturally into place. This first introduction video explains that control flow.
 
Slides and source code are available on Lucian's blog.
