Hello-
Thank you for your email and for your interest in the LCDS.
We currently are not able to support right-to-left script languages such as Arabic in the LCDS; however, we do plan to include right-to-left text support in the tool
in the next year. We’re moving our Silverlight elements into Silverlight 4.0 in order to lay the groundwork for right-to-left text support.
For now, the LCDS is localized in Brazilian Portuguese, Chinese (Simplified), Russian, Hindi, Turkish, Spanish, and Polish.
Thanks again for your interest in the LCDS.
Stephanie
