I use CR for VS 2010 / 2012 / 2013.
I found in some posts this response, so i should install RAS, is this right?
"The SDK that comes with CR.NET does NOT support RCAPI (Report Modification and Creation API). The ReportDocument class does not support creating a new report from scratch. It only supports loading an existing report into memory so that it can be printed or previewed. You have to use the report designer in CR.NET to create a new report.
If you want to create a report from scratch, you need to buy a license for RAS (Report Application Server) and then you have access to the RCAPI for CR.NET
