XAML to C# Converter

I need help to convert XAML TO C# in the following code. It was working fine at the design time. But I want to assign the values in the runtime.

Here is the XAML code:

< Image UITest:SupportAnimatedGIFBehviour.SupportAnimatedGif="True"/>

And the full source is in the following website:

For this XAML:

<Image Name="myImage"/>

Use this C# code:

SupportAnimatedGIFBehviour.SetSupportAnimatedGif( myImage, true );
