错误继续。桌面应用程序的代码：

private void LoadAssemblys()
        {
            var dir = System.AppDomain.CurrentDomain.BaseDirectory;
            Assembly MyHomeAssembly=Assembly.LoadFrom(dir + "/MyHome.dll");
            System.Type[] types = MyHomeAssembly.GetTypes();
            System.Type primaryTyp = types[0];
            foreach (System.Type t in types)
            {
                if (t.Name == "MyHomePage")
                {
                     var obj = MyHomeAssembly.CreateInstance("MyHome.MyHomePage", true);
                }
            }
        }
