Feel free to use this plugin as you like. It is a simple plug in that shows information about the Twitter user right inline with the Tweet. This post will explain what the Sticky plugin does and of course I’ll share the plugin with you. I’ll follow up with another post to explain how to create a plugin using the Seesmic Desktop platform, Visual Studio 2010, and Expression Blend.

Mark has worked on the text aspects of Silverlight since the first version. Here are just a few of the areas that Mark covers:

1. Overview of RichTextBox vs. TextBlock and TextBox for rich content
2. Wire-up logic for applying formatting
3. Inline UI elements
4. Using text position to point for simple and complex operations [...]

He creates several demonstrations using the new DataStore and conditional behavior features in concert with several new behaviors including ChangePropertyAction, ControlStoryBoardAction, SetDataStoreValueAction, and the custom Mouse3DBehavior. Adam also shows how to create a custom behavior using code. Don't miss this episode as Adam discusses how behaviors can make the UI developer's job much easier.

We have had a good response to the free 8 module Silverlight Training Kit we released on Channel 9 back at MIX and that Scott Guthrie announced. We have since updated at the Silverlight 4 Launch with some new content and fixes. We’ve also found 2 issues since then that you might run across. I’ve corrected these in the source and will update them on the Channel 9 site in our next round (which I hope to include VB version of the courseware, too!)

They discuss the road their teams took to create RIA Services, some of the decision points that helped shape the product, and the high level of community involvement in the product's evolution. They also demonstrate some of the features of RIA Services and give a glimpse at what the future may have in store for it.

This morning we published the final release of the Silverlight 4 Tools for Visual Studio and WCF RIA Services.  In April, when Silverlight 4 was released, the tools were still in “RC” status.  Today, they are no longer and are officially released.  There is no new update to Silverlight itself, but these tools are the final bits of this version.

This is a great explanation and walk through of how to open RIA Services domain services to clients, including:

• Silverlight clients (of course)
• Creating an OData endpoint and showing how Excel can use it
• Creating a SOAP endpoint to a domain service and using it from a Windows Phone 7 application
• Creating a JSON endpoint and having an AJAX application talk to it

The key here are the DisplayMemberPath and SelectedValuePath properties. These apply to the object that each item in the ComboBox is bound to. In other words, these properties are set to the State, not the ObservableCollection<State>. Also, notice these properties are not data bound, they are instead set to the name of the properties respectively. We do not want the values of the properties here, we want the actual name of the properties (which is why it is called DisplayMemberPath and SelectedValuePath).

The PathListBox is one of the newest features available in Expression Blend and Silverlight 4. It redefines how users look at lists of data as it breaks the mold of a list "box" and opens the possibilities to use any shape or path. Don't miss this episode and be sure to download Adam's sample code.
