With the version of SQL Server Data Tools included with SQL Server 2012 you could create a report definition and copy the .rdl into the folder below and it would appear when you created a new project item.
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\ProjectItems\ReportProject
I'm trying to achieve the same with Visual Studio 2017 and the Report Project extension though this does not appear to work when I copy the file to the folder below:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\PrivateAssemblies\ProjectItems\ReportProject
How can I get template report items to appear for report projects?
