PathListBox control comes with Blend 4 SDK in Silverlight 4. PathListBox allows any elements to be layed out along the path. Just imagine putting letters around the circle and then animating it.

My speculation based on Mix 2010 Sessions...

downloads/PassingLargeText.zipWe will look at passing large text to Silverlight using InitParams and then we will take a look at using Fiddler to see what gets passed into Silverlight.

Using WebClient and AssemblyPart we can dynamically load any assemblies. This is greate techniques to use for designing plug and play type of Silverlight application. Also this is greate optimazation technique to make the xap file smaller and lazy load assemblies that might contain business logic.

Imagine that you have silverlight that does not require redeployment and only thing you have to redeploy is your reflectively loaded assemblies during runtime!

In MSDN about Silverlight 3, there is new feature called Application Library Caching.This tutorial is to explor this new feature and verify that it does work.

Question is why is this compelling new feature?

In Silverlight 2 there were couple of ways to take advantage of browser caching and it was to download resources. In Silverlight 3 there is support to accomplish this out of the box. When application gets compiled and re-deployed we do not want the resources to be re downloaded unless the resources such as images changed because it takes too much time. Just imagine having WMV as resources and you are forced to download everytime new Silverlight application is deployed!

Silverlight has nice support for full screen. Only problem is that when Silverlight application goes into full screen mode none of the controls will scale properly. One of the biggest advantage of using vertor graphics is that when the resolution increases controls are expected to increase and not lose the quality.

So how can we scale the elements when Silverlight application goes into Full Screen mode?

There is really nice WPF pixel Shader Library in codeplex (http://wpffx.codeplex.com/) that can be used in Silverlight 3. See the demo below for the list of following effects in action: Banded Swirl Effect, Bloom Effect, Bright Extract Effect, Color Tone Effect, Contrast Adjust Effect, Directional Blur Effect, Gloom Effect, Growable Poisson Disk Effect, Invert Color Effect, Light Streak Effect, Magnify Effect, Monochrome Effect, Pinch Effect, Pixelate Effect, Ripple Effect, Sharpen Effect, Smooth Magnify Effect, Swirl Effect, Tone Mapping Effect, Toon Shader Effect and Zoom Blur Effect.

My favorite is Zoom Blur Effect. What's yours?

Threadpool allows you to spawn multiple background thread allowing you to process for in this example to allow multiple images to be downloaded.

You can apply this simple but very poweful example to spawn worker threads to perform time consuming executions.

Using Style Element is similar to how you are using HTML and CSS. This example will cover brief overview of how this works.

Go ahead download the sample and play around with Style.

We will look at how to stream xml file from URL and display to simple textbox. Description seems to be simple and trivial but doing it right take little work.
