We have walked through the cider features, we have discussed its integration with Blend and the sweet spots for each tool … to most users that is plenty, but there is a side to Cider that eventhough you might not see a lot is very important for the ecosystem and our long-term vision for Rapid development of WPF apps: the design-time extensibility.
By example, extensibility refers to:
- Providing hooks (or APIs) so you can check if your code is running inside the designer — for example at design-time, you might not have access to data that your app expects.. or at design-time you might want your controls to not animate or play video as soon as they are loaded (when at run-time you might want that)..
- Support for licensing ( so control vendors can sell you a control that makes your life easier)
- Support for custom property editors ( say you bought that control from a 3rd party), making it as easy as possible to set the right properties so the control is configured for run-time is obviously a goal of the tool vendor or framework vendor..
For this part, I don’t have a screencast or a write-up because Jim Nakashima recently posted his TechEd session on Designer Extensibility …. Every thing you need (or more than I know) is covered there and I can’t say it any better so let’s give him the floor ..
Jim also posted his code samples for the session .
This closes the Cider series.. Let me know if I missed some thing that was important to you.
