How to setup a Multi-Project Solution?

[Faraz Ahmed Qureshi]

Hi!

While I can have a single project solution successfully built with the Target Framework  being set to net 8.0-windows in .csproj file, How to have the same or similar type of Solution but with multiple projects consisting separate projects e.g. different ones for:

- Core purposes like carrying out procedures e.g. AutoOpen / AutoClose etc.

- UDFs

- UIs (e.g. Ribbon and Forms / WPFs)

- Procedures

Since have failed to achieve the same despite of adding projects references in the .csproj file, any sample project or guidance shall be appreciated.
