c# - Autofac won't resolve class from external dll -

i'm trying create application utilizes autofac , loads external dlls. following code works, if dll located in same folder , program ran same folder:

builder.registerassemblytypes(assemblies.toarray()).             where(t => typeof(iimageconverter).isassignablefrom(t)).             instanceperlifetimescope().asimplementedinterfaces(); 

now if try run program different location set working directory directory dll located, autofac finds , loads dll, doesn't resolve run it:

using (var scope = _container.beginlifetimescope()) {     var processors = scope.resolve<ienumerable<iimageconverter>>();     foreach (var process in processors)         process.process(); } 

those autofac lines have. interface defined in shared library , each module implements default. missing?

thanks in advance!

it depends on values assigned assemblies. autofac not load dlls, scans loaded assemblies.

read dynamicic module loading determine how load external dlls.
