Mário Meyrelles is right.

It's all about Microsoft.ReportViewer.Common.dll and Microsoft.ReportViewer.WinForms.dll version. Please make sure that you referred to correct or latest dll version. e.g. for VS2013, we should use version 11.

C:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.Common\11.0.0.0__89845dcd8080cc91\Microsoft.ReportViewer.Common.dll

C:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.WinForms\11.0.0.0__89845dcd8080cc91\Microsoft.ReportViewer.WinForms.dll
