I have an AspNet MVC project in Visual Studio 2017 that was previously developed in Visual Studio 2015. This project contains many rdlc files that were working fine until I edited one of them. Now, when I try to download the pdf from the rdlc edited I get this error:

The definition of this report is not valid or supported by this version of Reporting Services. The report definition may have been created with a later version of Reporting Services, or contain content that is not well-formed or not valid based on Reporting Services schemas. Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition' which cannot be upgraded.

The rdlc edited changes its namespace from http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition to http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition

The project is running with net framework 4.6.2 and it has installed Microsoft.ReportViewer.Runtime.Common.12.0.2402.15 and Microsoft.ReportViewer.Runtime.WebForms.12.0.2402.15 nuget packages

I had the same problem and I solved it uninstalling the nuget packages Microsoft.ReportViewer.Runtime.Common and Microsoft.ReportViewer.Runtime.WebForms and installing the package Microsoft.ReportingServices.ReportViewerControl.WebForms.140.340.80. I would like to highlight that I had to add a reference to System.Windows.Forms because there is a dependency in the class ReportDataSource that I use to render my reports
