Help me Convert this WPF to Silverlight

I am interested in a Charles Petzold C# example that shows how to do a fisheye effect ( http://www.charlespetzold.com/blog/2009 ... light.html ). The XAML code samples are in WPF but I want to try this in Silverlight.

When I try to create the XAML code in Silverlight, the compiler complains in two locations:

<Style TargetType="{x:Type Button}">
Error 1 The type 'x:Type' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

<Style.Triggers>
Error 2 The attachable property 'Triggers' was not found in type 'Style'.

How do I convert this to Silverlight?
