将程序集加载到应用程序域，但收到无法加载文件或程序集异常

我正在尝试动态加载一些程序集，如:

using (var svc = new MyClient()) // MyClient is proxy to a WCF service
{
    var bytecode = svc.GetAssembly();
    var assembly = Assembly.Load(bytecode);
    var dependencies = svc.GetDependencies();
    foreach (var dependency in dependencies)
    {
        Assembly.Load(dependency.Bytecode);
        Console.WriteLine("loaded {0}", asm.FullName);
    }
    var type = assembly.GetExportedTypes().First();
    var ctor = type.GetConstructor(new Type[0]);
    var obj = ctor.Invoke(new object[0]);    // get an exception here
}

然而，当调用tor时，我得到一个异常，CLR试图加载依赖的程序集。我已经在for循环中将依赖项加载到app域中。如何修复此异常?
