ASP MVC2部署到IIS7时出错
ASP MVC2部署到IIS7时出错
提问于 2011-04-26 10:23:13
在我将应用程序部署到IIS7服务器之后，开始看起来还不错，并且可以显示登录页面。但在用户输入用户名和密码后，我必须通过DB连接验证用户。此时，它会显示错误(已附加)。我猜这个错误是由EntityFramwork加载DB数据时的反射引起的。
我的服务器已经安装了.net Framework3.5 sp1。
另一方面，我已经尝试了另一台服务器。如果服务器已经安装了VS2008和MVC2 VS2008软件包，则该服务器可以在IIS7中正确运行应用程序。
我的目标是在只有.net Framework3.5的IIS7服务器上运行这个应用程序。
请帮我解决这个问题。
错误数据：
Server Error in '/FDDV_demo' Application.

我终于解决了这个问题。主要原因是项目遗漏了一些程序集引用。我将以下代码添加到登录函数中，以找出反射类型加载异常。再次感谢大家的帮助。
try{
//Do your work
}
catch (Exception ex)
{
ReflectionTypeLoadException exception = ex as ReflectionTypeLoadException;
if (exception == null)
System.IO.File.AppendAllText("C:\\TestLog.txt", "Not a ReflectionTypeLoadException ex.");
else
{
foreach (Exception loaderException in exception.LoaderExceptions)
{
System.IO.File.AppendAllText("C:\\TestLog.txt", loaderException.Message);
System.IO.File.AppendAllText("C:\\TestLog.txt", loaderException.StackTrace);
}
}
return true;

我隐约记得，当我从MVC2升级一个项目时，在我的web.config中遇到了一些版本问题，MVC3也有类似的问题。
尝试启用融合程序集日志绑定，看看是否可以找到加载失败的原因。

不久前我发现了一个脚本，可以让我在IIS中更好地处理融合日志(我遇到了一些问题，因为它在IIS中不能运行)。
