c# Assembly.LoadFrom with dynamic AssemblyResolve

I'm kind of stuck with dynamically loading plugins:

Theory: (Plugin) Dlls in a specific folder:

foreach(string path in Directory.GetFiles(...))
{
    Assembly myPlugin = Assembly.LoadFrom(path);
    foreach(Type type in myPlugin.GetTypes().Where(t => typeof(myPluginBaseClass).isAssignableFrom(t)))
    {
        Activator.CreateInstance(type);
    }
}

So far so good. Now there are issues with additional references in those assemblies, which can be solved by catch(ReflectionTypeLoadException) (to removed all null Types) and AppDomain.CurrentDomain.AssemblyResolve += ... (to manually look for those missing dlls)

Now here is the issue: The referenced missing assemblies are specific for each implemented Plugin, so I need a individual search behavior implemented in each Plugin. My ideas / solutions so far:

I hope you can help!

Thanks in advance! Robin

Create domain seems to be adequat solution for plugin pattern.

You don't really need to define AssemblyResolve, you can simply configure the directory where AppDomain can find dependencies.
