title: Upgrade RDLC from 2008 to 2010 (2005 report to 2008 report) Error
body: <p>I have multiple reports that have been created over the years and anytime a RDLC file is opened in the VS2010, it is asking for an upgrade. I have seen many posts about changing the .config file, but these files are not using config files since they are application based. I have Microsoft.ReportViewer.Winforms, .Common, .ProcessingObjectModel and, .WebForms 9.0 and 8.0 installed on the lab machine. </p>
  
  <p>After upgrading a report and trying to run it on the lab machine ( ms server 2008) I am returned an error of: "The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition' which cannot be upgraded. </p>
  
  <p>Does Report Viewer 2010 Redistributable Package fix this issue? I cannot find a distinct answer. If not, is there another workaround without changing server modes from local to server? </p>
