ApplicationManager.CreateObject无法在新的AppDomain中加载程序集

Question

我正在尝试开发一个Web应用程序，该Web应用程序可以根据请求将（Dispatcher）分发到另一个Webapp的多个版本。 为此，我正在使用ApplicationManager.CreateObject来创建运行有问题的Web应用程序的新AppDomain，但是新的应用程序域似乎无法加载Dispatcher的DLL（并且我将DLL复制到了Web应用程序的bin目录，所以我很确定它在那里）。

var version = "version";
var path = @"C:\code\devel\webapp";

// Copy host assembly to target webapp so that 'Host' is available
var assembly = Assembly.GetExecutingAssembly().Location;
var target = path + "\\bin\\" + Path.GetFileName(assembly);
File.Copy(assembly, target, true);

var manager = ApplicationManager.GetApplicationManager();
var obj = manager.CreateObject(version, typeof(Host), "/", path, true, true);

这是融合日志：

Assembly manager loaded from:  c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorwks.dll
Running under executable  C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\9.0\WebDev.WebServer.exe

Appbase似乎指向开发服务器的根目录，而不是传递到ApplicationManager.CreateObject的路径，它似乎只是在开发服务器下搜索目录，这似乎很奇怪。 关于如何使新AppDomain在Web应用程序的根目录而不是在开发服务器下搜索DLL的任何想法？

看起来（至少就我们而言）这是错误的方法：使用反向代理是正确的方法。

反向代理的优势在于他们是在HTTP架构的“模式”，他们拯救我们不必确保ASP.NET运行时真的在运行实际的Web应用程序的AppDomain的正确配置。

我们目前正在研究ProxyMachine ，它是一个可高度配置的TCP反向代理， GitHub似乎在此方面取得了一些成功 。
