We are pleased to announce the release of version 1.0.1 of the ArcGIS Viewer for Silverlight. This is a quick-turnaround maintenance release to fix critical bugs that have been identified since the release of version 1.0. The Viewer team has worked hard to address these issues quickly in order to minimize their impact on your Silverlight Viewer applications. The issues addressed include:
- ArcGIS Viewer for Silverlight Applications do not load on Windows XP clients if data containing characters with diacritical marks (e.g. ü, ä, ñ, etc) is included in the map
- Several localization issues related to the forthcoming localized releases of the Viewer
Seamless upgrade has been integrated into the setup for version 1.0.1. If you currently have version 1.0 final installed, you can upgrade to the latest version by simply running the setup for version 1.0.1. The Application Builder and all deployed Viewer Applications will be automatically upgraded to version 1.0.1. All pre-existing configuration and customizations will be preserved.
As always, you can check out the ArcGIS for Viewer for Silverlight Resource Center for information on getting started, help using the product, and samples to show you how to build add-ins for the Viewer. And if you have questions, be sure to take advantage of the ArcGIS Viewer for Silverlight forum to get help from the community.
Enjoy!
The ArcGIS Viewer for Silverlight Team

Hi Oleg,
The language packs are currently in release certification. It will take a bit of time for each language/OS combination to be tested, but we hope to have them to you soon.
