Getting error : This operation is not supported on a report server that runs in native mode

Hi,

I have installed SQLServer2008 Standard Edition in my system.

Using SSRS 2008.

I have added http://<serverName>/ReportServer/ReportService2006.asmx as web reference in my project.

If i consume any method in ReportingService2006 am getting below error . 

This operation is not supported on a report server that runs in native mode. ---> Microsoft.ReportingServices.Diagnostics.Utilities.OperationNotSupportedNativeModeException: This operation is not supported on a report server that runs in native mode.

How to solve this problem?

Thanks,
