What's different about these IL lines? (Fody output assembly)
Dotfuscator uses ildasm to get IL code, which is what it then performs its obfuscation on. Dotfuscator has been choking on one particular assembly. This is the only assembly in the solution which uses Fody, an IL weaver, to "weave" additional CIL into the assembly after it is compiled. Interestingly, Dotfuscator says which line it has a hard time with, and that line is always syntax highlighted differently by ReSharper in Visual Studio. There's always more than one line highlighted that way, but Dotfuscator always errors on the first one... Interesting.
If you tell me why ReSharper thinks these lines are different, maybe I can figure out why Dotfuscator can't obfuscate this assembly, and only this assembly out of 100+ others in the solution.

Solution
Fody is evil.
Fody is an IL weaver. It can add code to your assembly after it is compiled. The problem is, the PDB file ended up mismatched with the assembly because of Fody, so ILDASM ran into a problem producing valid IL code. Delete the PDB and Dotfuscator works again.
