What is the difference between RDL and RDLC formats?A: RDL files are created by the SQL Server xxxx version of ReportDesigner. RDLC files are created by the Visual Studio xxxx version

of Report Designer. RDL and RDLC formats have the same XML schema. However, in

RDLC files, some values (such as query text) are allowed to beempty, which means that they are not immediately ready to bepublished to a Report Server.

RDL reports are HOSTED reports generally. Thismeans you need to implement SSRS Server. RDLCreports are CLIENT CONTAINED reports that are NOTHOSTED ANYWHERE. Generally this is an extension of theRDL language meant for use only in Visual Studio Client

Applications. It exists in Visual Studio when you add a'reporting' item.
