I'm pretty sure I have all the right flags and everything set according to Microsoft Docs, however the UI dlls are not being included in the single file exe.

It's great for legacy .NET projects. Newer frameworks have single-file executables as shown in their documentation

AFAIK, you can't. Self-Contained does not mean One-Single-File. It means that all the dependencies will be next to your EXE so you won't need to install runtimes to the target device.
