The report definition has an invalid target namespace rsInvalidReportDefinition
<p>I have created a ReportProject with Visual Studio data tools 2015.  When I create a report.rdl file using the report wizard, the rdl file has schema for 2016.  My reporting server is of version 12.0.4213.0. </p>

<p>How can I create a report.rdl which is compatible with my reporting server.  I tried changing the TargetServerVersion by right clicking the project -> properties and changing the targetserverversion to "Sql server 2008 R2, 2012 or 2014". But this doesn't work either.</p>
