我正在处理使用.Net framework 4的传统c＃应用程序。该应用程序使用WebBrowser控件和引用＆＃34; Microsoft HTML Object Library＆＃34; （MSHTML）。当前版本部署到Server 2003，只有在安装.Net framework 2 SDK时才会运行。
推动是将应用程序部署到服务器2008但没有框架SDK。但当然，该应用程序不会运行。生成的错误是＆＃34;无法转换类型为＆＃39; System .__ ComObject＆＃39;的COM对象。 to class type＆＃39; mshtml.HTMLFormElementClass＆＃39;。＆＃34;我意识到可以通过转换到接口来解决这个特定错误。事实上，我做了这个更改，应用程序运行直到下一个mshtml转换错误。在整个应用程序中有超过200行相似的代码，没有很好的方法来测试所做的更改。
我已经使用Fusion Log Viewer来了解正在加载的依赖项，并且发现当从Visual Studio 2010启动应用程序时，mshtml正在加载CustomMarshalers，或者如sys管理员发现的那样，Visual Studio 2010在启动应用程序之前安装在服务器2008上。我的直觉是，无论是否存在Visual Studio，我都需要使用mshtml加载CustomMarshalers。
Visual Studio导致mshtml加载CustomMarshalers的含义是什么？我怎样才能从代码中实现这一点？
