"Oslo" SDK January 2009 CTP

In the post I'll write about new "Oslo" CTP.

Last Friday Microsoft has released  "Oslo" SDK January 2009 CTP.  Elements of new SDK and changes are described here.  Some information I have read:

What's New?

• Token Actions for MGrammar
• MGraph syntax supported in MGrammar RHS
• Additional M Collection Members

Breaking changes:

• CaseSensitive attribute has been renamed to CaseInsensitive and doesn't require arguments.
• Repository: some schemas have been renamed,  you can no longer build all the supplied Oslo models using the /t:Repository option

I wait for more information about new CTP.

PDC version of "Quadrant" - some limitations and questions

"Quadrant" is a visual tool for models created with the code name “Oslo” platform. There's a PDC virtual machine with "Oslo" and "Dublin" and it includes pre-alpha version of  "Quadrant", documentation and some Hands-On Labs. "Quadrant" seems to be cool, but PDC version has some limitations.

1. You can create instances and custom views of models, but editor for creating model schema with "M" language will be integrated in next builds.
2. You can make new model with "M" using Intellipad or Visual Studio and import compiled "M" image to "Oslo" repository. But current version of  "Quadrant" can't read models other than Microsoft samples !  I have tried to read my model and "Quadrant" Explorer has found it in Microsoft.Repository.Load only. Other people also have the same problem.
3. What about more advanced customization than changing icon, category, default view, size of columns, adding property to display? How can I change f.e shape for instance of model? How can I write custom designer like workflow designer or business process designer?

I wait for next CTP of  "Quadrant" to read my models from repository.

BTW I'm keen on "Oslo" technology, so I wrote post with my questions about "Oslo" in community forum.

Silverlight Toolkit December 2008

This post will be about new version of Silverlight Toolkit.

In the December 2008 release Silverlight team has included: 100 new features and bug fixes, 3 new themes (Whistler Blue,  Bureau Black, Bureau Blue), better design-time support, charting improvements, and enhanced UI Accessibility features.

     

For more information about changes  you see:

• Silverlight Toolkit December 2008 changes 
• Silverlight controls toolkit december released
• Silverlight AutoCompleteBox: What’s new in the December release
• ilverlight Charting gets a host of improvements [Silverlight Toolkit December 08 release now available!]

Silverlight 3: H.264 video + 3D hardware acceleration !

This post will be about new features in next version of Silverlight, which is planned for availability in 2009.

On November 16th Scott Guthrie revealed Silverlight 3 will include:

• H.264 video support
• 3D support and GPU hardware acceleration (That sounds great !)
• richer data-binding support
• additional controls

These are just a small sampling of the improvements.

Future of Silverlight

Last week I saw three interesting PDC presentations about Silverlight. So in this post I write about Silverlight future components and mobile edition of the technology.

PDC Silverlight sessions I've seen:

Microsoft Silverlight 2 for Mobile: Developing for Mobile Devices

Silverlight 2 for mobile supports .NET programming model. You don't need to change code of your Silverlight 2 application, but you can recognize displaying device (DeviceInformation class) to do some actions (for example making full-screen only for mobile devices). You can also use wrapper to recognize gestures.  Public CTP will be available  at Q1 during 2009. Excellent session with many practical demos! (at the end very interesting demo with ducks which depend on position of mobile phone).

Microsoft Silverlight Futures: Building Business Focused Applications

Second part of this session 'Futures'  is quite interesting. In the future Microsoft will add page navigation and frameworks for business applications (for example validation, authentication, business objects, data paging). Business Logic Framework will make building n-tier applications simpler. You should see practical demo with these new components. Team is also working on editable Visual Studio Silverlight designer, design time databinding support, core platform enhancements and many new controls.

Silverlight Controls Roadmap

 

This session is about Silverlight Toolkit (WPF controls: DockPanel, WrapPanel, TreeView, Expander, Label, ViewBox, HeaderedContentControl, HeaderedItemsControl + new controls:  AutoComplete, Charting, NumericUpDown + 6 themes with Implicit Style Manager). IMHO AutoComplete control is very useful and cool!  Silverlight Toolkit will be updated with new components ( Accordion, ListView) and many improvements (f.e charting, designer).  What's more - Microsoft thinks about making more new controls (MIX 2009 - MediaPlayer, TimePicker, Carousel, Rating, MaskedTextBox; in future: InPlaceEditing, AppoinmentCalendar, ImageMap, FileUpload, Menu, Slideshow).

Silverlight - value inheritance

This post will be about value inheritance of dependency properties in Silverlight.

You cannot write custom dependency property with inheritance. There is the fixed set of predefined properties with value inheritance, for example: FontFamily, FontSize, FontStretch, FontStyle, FontWeight, Foreground.  There was a problem with performance and Silverlight team did a number of optimizations specific to those particular properties. All properties have the same precedence order:

1.  animations -> 2. local value (and binding) -> 3. templated property -> 4. style -> 5. value inheritance -> 6. default value

BTW,  Silverlight Toolkit introduces one more way to customize controls  - themes.  Theme  has lower priority than style, but higher than value inheritance.
