Unfortunately, the code being migrated is a quite a bit of legacy so I can’t really create a sample project to replicate the issue but I can provide a stack trace, which unfortunately seems to be deep within Ninject.
The type initializer for ‘NServiceBus.Unicast.Messages.MessageMetadataRegistry’ threw an exception.
