When I use visual studio 2008 and do a new project I can select the type of project as Business Intelligence project. From here I can select a report server project.
<Just read that the SQL team is generally behind the vs.net team. So you have to use Visual Studio 2008 to develop reports. I guess the next version of SQL should bring an add on to VS.
See the graph also from MSDN:
You need to install SQL Server 2012 with Reporting Services to enable Business Intelligence projects in Visual Studio 2010. You also need to install SSDT for Visual Studio 2010 to work on the same.
