Tomaz Kastrun shows how you can install support for SSIS, SSAS, and SSRS with Visual Studio 2019:
Visual Studio 2019 brings new installation of SQL Server Integration services and SQL Server Analysis Services and SQL Server Reporting Services.
There is no need to download SSDT (SQL Server Data Tools for Visual Studio) as used to do with Visual Studio 2017 or previous versions.
Installation is pretty easy once you know where to look.
