Today, I try to upgrade my first sample in this blog to Silverlight 2. Out of my expectation, the code work perfectly and actually I can run the application directly after copy and paste the files.
Anyway, there are some interesting findings when updating the code. I will try to list them all during the upgrade.
Comparison
What’s the difference?
- DispatcherTimer vs CompositionTarget.Rendering

DispatcherTimer vs CompositionTarget.Rendering
In Silverlight 2, it’s much simpler to simulate the enter frame event by using CompositionTarget.Rednering. It enables you to modify the frame rate easily as well.
// C#
// New Method
Application.Current.Host.Settings.MaxFrameRate = fps;
CompositionTarget.Rendering += new EventHandler(CompositionTarget_Rendering);
void CompositionTarget_Rendering(object sender, EventArgs e)
{
// do your stuff here
}
// Old Method
DispatcherTimer timer = new DispatcherTimer();
timer.Interval = new TimeSpan(0, 0, 0, 0, 1000/fps);
timer.Tick +=new EventHandler(_timer_Tick);
timer.Start();
void timer_Tick(object sender, EventArgs e)
{
// do your stuff here
}
Shares and Enjoy~

Thanks for you public code and share idea to create 3d text space. I try to download your source code and try to run this application but i found some error about “compositiontarget”.
The error message is “The name ‘CompositionTarget’ does not exist in the current context”. Please help me to find out or find the best solution to solve this problem.
For another way, i try to go to bin folder on directly path of this application and click on the testpage.html. The page will be open and alway show silverlight link to download Silverlight 2 Beta 2 v.2.0.31005.1 .
