I recently wrote a post about i18n in ASP.NET. Today while I was searching for some better articles about this issue I found Microsoft Middle East MSDN site. This web site is built to help middle eastern developers which their native language is Arabic. Since Persian language, like Arabic, is a right-to-left (RTL) language I think many articles and resources on this web site can help Persian developers build more internationalized windows and web applications. Don't miss it!

UPDATE: Dr. International blog and Microsoft Global Dev. are also interesting :D
