Visual Studio 2008 has been localized into Arabic, Czech, Hebrew, Hindi, Polish, Tamil, Turkish, Malayalam and Oriya as a free "CLIP" download package.
"CLIP" stand for "Captions Language Interface Pack". It's basically an add-on with localized user interface that you install on top of the English version of Visual Studio. The CLIP package allows you to see translations of menus, button and so on as tooltips when running Visual Studio.
It's designed for users who use the English version, but want to see the most common user interface in their own language as well.
The translations in the CLIP package are a joint-effort between Microsoft and local communities.
Here are a couple of screenshots of what this looks like when you are working in the product (apologies in advance for the poor image quality):
When you hover your mouse over a menu or command, a separate box (or a tooltip depending on your setup) will display the translation in the local language. You can also add your own translation for user interface items.
The CLIP packages are available as free downloads from the Local Language Program or directly from these links:
