A Class for use when embedding assemblies that may have embedded assemblies in them (this will take care of all of it, just run PreLoadAssemblies() once then add CurrentDomainAssemblyResolve to the current domain AssemblyResolve event like so (NOTE: This must be done BEFORE anything is actually running): AppDomain.CurrentDomain.AssemblyResolve +…
