The other day, I installed Microsoft SQL Server Data Tools - Business Intelligence for Visual Studio 2013 (SSDT: replacement for BIDS) and started using the reporting features in VS2013 .
Successfully created a project using the Project Server Project Wizard.
However, later I needed SQL Server 2014, then I downloaded and installed the developer version. (in case this could cause a problem)
Now the report server project is missing in VS2013 , and I canβt just get them back.
Now my VS2008 has the functions I want: 
But no trace in VS2013 Professional : 
Any suggestions?
Additional unsuccessful approaches I took
- Refurbished SQL Server Data Services.
- An attempt to remove this service, which led to many problems, including, cannot install this service, since all the checkboxes are checked and grayed out during installation and can no longer pass this level.
- Trying to remove all related components that may allow me to install SSDT-BI for Visual Studio 2013 again, but did not help. This is the Microsoft guide I took for this: Removing SQL Server Data Components
- Edited the entire installation of SQL Server 2014 (64-bit) from the installation media.
- I tried restoring unregistered VS2013 templates using
devenv.exe /InstallVSTemplates , following this guide from Microsoft / InstallVSTemplates (devenv.exe) .
