CorLib not found

The problem

You’re getting an error like Could not load file or assembly CorLib Version=x.x.x.x, ....

Solution

This usually means a framework mismatch. You’re running a BitMono build that targets one runtime (say the .NET / .NET Core build), but the file you’re obfuscating is meant for another (say Mono). When the runtimes don’t line up, BitMono can’t resolve the core library.

Fix it by using the BitMono build whose target framework matches the file you’re protecting. For a Mono target, use the .NET Framework build of BitMono. See The module is built for … for the full framework-matching rundown.
