Whirlwind 14: What's new in C# 4 - Events

Download

How do I download the videos?

• To download, right click the file type you would like and pick “Save target as…” or “Save link as…”

Why should I download videos from Channel9?

• It's an easy way to save the videos you like locally.
• 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.

Right click “Save as…”

• High Quality WMV (PC, Xbox, MCE)
• MP3 (Audio only)
• MP4 (iPod, Zune HD)
• Mid Quality WMV (Lo-band, Mobile)

ISV Architect Evangelist Bruce Kyle of Microsoft and MVP Stuart Celarier explore the new languages features in C#. It's a Whirlwind Tour of the important language features of C# 4. Stuart describes each major feature and why it is useful. But doesn't get into best practices nor suggested usages. Just the facts about each feature.

Whirlwinds are bite-sized webcasts, generally shorter than 15 minutes. You can start anywhere in the series to learn about the parts you're most interested in.

This session on C# 4 shows how the compiler handles eventing. The compiler no longer sets locks on events, instead uses a compare and swap technique. Stuart compares C# from .NET 3.5 and .NET 4 to show the differences and explains the implications for your existing code.
