About a year and a half ago, I was architecting a modular monolith and obsessing over performance. I'd been using MediatR for years, but I wanted something faster. I discovered Mediator by Martin Othamar - a SourceGenerator-based implementation that promised better performance through compile-time code generation.

I think people who last looked at C# 10 years ago or haven't adapted to new language features seriously don't know how good C# is these days.
Switch expressions with pattern matching are absolutely killer[0] for its terseness.
Also, it is possible to use OneOf[1] and Dunet[2] to get access to DU

It's a WinForms application. However, it is indeed somewhat user-unfriendly to distribute (untrimmable) WinForms applications in a self-contained form.
It's usually much better to build them as runtime-dependent but single-file binaries.
E.g. 'dotnet publish -p:PublishSingleFile=true --no-self-contained' produces a 5.9 MB binary (but obviously needs a .NET desktop runtime installed, it helpfully offers to do so on launch if it's missing).
I assume modifying the solution to use https://github.com/kant2002/WinFormsComInterop + NativeAOT would result in ~30-40MB binary as it packages a GUI framework effectively. It could also help with just self-contained and getting trimming to work.
There is a bit of learning curve to all sorts of ways you can build an application with .NET but that's what you pay for having flexible choices over more limited options with Java or Go.
