Hi, what is the minRuntimeVersion of Silverlight required for the current version of Telerik Silverlight Controls? Many of our users are still on Silverlight 1.1 (using non-telerik legacy silverlight controls) -- in your experience, is the upgrade from 1.1 to higher version transparent/automatic (even on locked desktops)? Thanks

Hello Amit,

You need the Silverlight 3 runtime in order to use RadControls for Silverlight. The installation should not take more than 1-2 minutes.
Note: Silverlight 3 is backward compatible with Silverlight 2.0 and Silverlight 1.0. If you have developed products using Silverlight 1.1, there is a high chance the products would stop working once you upgrade to Silverlight 3.

Let me know if you have additional questions on that matter.

Best wishes,
