【问题描述】：
我做了一个简单的 ajax 服务（基于 json）来从数据库中获取一些数据。 问题如下：
在本地主机上：在 Visual Studio 中编程/编辑 aspx 页面并在浏览器中查看结果时，它可以正常运行 5-6 次编辑 aspx 页面，然后开始失败。直到我去我的网络服务接口类做一些事情（比如在某处放一个换行符）并重新编译它。问题得到解决，循环继续......
当我在 fire bug 中跟踪失败的请求时，我发现 500 内部服务器错误： [FileNotFoundException：无法加载文件或程序集“App_Web_lbgnha4m，版本=0.0.0.0，文化=中性，PublicKeyToken=null”或其依赖项之一。该系统找不到指定的文件。] *下面的完整堆栈跟踪。
我不确定，但看起来这个文件“App_Web_lbgnha4m”是临时生成的，因为每次我通过重新编译代码来修复这个错误。一段时间后，它又以新名称“App_Web_blahblahblah”回来了
我最担心的是，当我将解决方案部署到临时服务器时。该服务运行良好（比如一天），然后出现同样的错误，非常惊讶在部署后不接触文件的情况下出了什么问题）。显然我不能每天都部署解决方案来解决这个问题......
任何建议请帮助......
