IReportDocument is ambiguous after upgrading to Q3 2012

[Nagendra]

Hi Team,


I have been facing an error as IReportDocument is Ambiguous in namespace 'Telerik.reporting' 

I have removed all my old versions and installed new Telerik reporting Q3 sp1 2012 after this change am getting this error.

Imports System.Collections.Generic
Imports Telerik.Reporting

Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim reportName As String = Server.UrlDecode(Me.Request.QueryString("ReportName"))

        If Not String.IsNullOrEmpty(reportName) Then
            Dim reportType As Type = Type.[GetType](reportName)
            Dim report As IReportDocument = DirectCast(Activator.CreateInstance(reportType), IReportDocument)
            Me.ReportViewer12.Report = report
            Me.Page.Title = reportType.Name

Hi Nagendra,

We have listed all introduced changes in the release notes and we highly recommend going through them prior upgrading to newer version especially if you skip several versions. You can review the following KB article that elaborates on the changes we have made and what should be changed: How to migrate your project to utilize the new ReportSource objects.

Kind regards,
Steve
