I have old projects that use ReportViewer with the following schemas;
xmlns="http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition" and mlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition"
Now I'm using VS 2017.
I have installed the Microsoft Rdlc Report Designer for Visual Studio through Extensions and Update, so, when I open a rdlc that was created on 2008/01/reportdefinition it works fine and I can modify it without problem.
However if I open a rdlc created on 2010/01/reportdefinition the report designer request me convert the rdlc to the newer version of: xmlns="http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition"
Can someone explain why this happens? And how I can get the 2010/01 version to behave like the 2008/01 rather than force me to upgrade.
