There are two AutoPBW.WPF.dll in the new release

[TheThief]

One in the "ref" folder, and on in the root. They are different sizes. Is this correct?

From testing, it doesn't need the one in the "ref" folder

This might help:

Hmm, so the ones in the "ref" folder are only used when dynamically compiling code? So for a WPF app that doesn't use Roslyn or anything like that, we could safely delete them, as you'd found? But once we start dynamically compiling code (say, FrEee mods), then we'd need them? I guess they're not really hurting anything to leave them there...
