How to force Visual Studio to regenerate files generated using Roslyn incremental generators?

[n9]

How can I tell Visual Studio to regenerate files that are generated using Roslyn's incremental generator?

Context: I have a solution with a project containing custom generators and another project that uses these custom generators. Changing and building the project with custom generators does not regenerate files that were generated by the generators. How can I tell Visual Studio to force regenerate these files?

Note: Currently I have as a workaround to restart Visual Studio.
