This SDK is a PubNub C# based client that is a Silverlight API to build realtime applications on PubNub. PubNub is a Push technology intended specifically for high-message-volume applications and games. It is a cloud-based, real-time messaging service for mobile phones, tablets, TVs, HTML5 web browsers and game consoles.
Evernote, the company that makes it easy to remember things, wants developers to use its API responsibly. To ensure this, the company is imposing rate limits on its API, it announced on a blog post. Those limits go into effect today (August 14) for non-production API keys. Existing users have until November 1 to adjust to the change.
