Indeed. I'm sure mine's not the normal case. I'm mainly just interested as it showing up as: "Collapsed methods without source. To view these methods, [blah, blah]".
Building in release mode took care of the .pdb file not being built, anymore. Even with that, it's still showing the source. It's not just showing the decompiled source; it's showing the source code (with comments, and everything).
I was under the impression that with no .pdb files, it would treat it as it would any other 3rd-party dll (e.g. NHibernate). However, it's somehow being really smart (good for it; bad for me) in locating the source files.
