Could not load type 'System.Windows.Controls.VirtualizingPanel' from assembly 'System.Windows, Version=2.0.5.0

[NTheOne]

Hello, I am converting my application to Silverlight 5 from Silverlight 4. I got following error while converting.

Could not load type 'System.Windows.Controls.VirtualizingPanel' from assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'.

Any help regarding that will be greatly appreciated. Thanks

Try removing the dll reference for System.Windows.Control and add it again.
