Hi @Haines, Karen,
There is no needs in any shells: Visual Studio 2015 Integrated Shell and Isolated Shell.
To setup an SSIS developer environment on your machine you need the following two components:
- VS2022 any edition.
- SQL Server Integration Services Projects 2022. Downloadable here:

Such setup will support SSIS run-time environment on a server for SQL Server 2016, 2017, 2019, and 2022.
