Silverlight 4 comapatabile with telerik Q3 2012

[Trish]

Hi,

I am using silverlight 4 and installed latest version if telerik Q3 2012  but when i add  telerik.reportviewer.silverlight

code does not recognise  this namespace using Telerik.ReportViewer.Silverlight and it gives error

 The type or namespace name 'ReportViewer' could not be found (are you missing a using directive or an assembly reference?)  

Is it compatibility issue ?  please help me.


Regards,
Trish
