With the new Assembly type scanner, when nancy search for the dll containing references to Nancy, where tries to load a dll that not are managed code(for example SQLite.Interop.dll or libzmq.dll) the method LoadAssembliesWithNancyReferences fromthe class AppDomainAssemblyTypeScanner throw a BadImageException. It's only need a try catch to not sh…
