Question

客户给了我这个错误日志，他告诉我他无法在我们的软件中阅读他的电子邮件历史记录。

我在错误日志中可以找到的内容如下：

At the time of the exception, the container was:                    

  Resolving Comp.Shared.Mail.Mail,(none) (mapped from Comp.Shared.Mail.IMail, (none))                   
  Calling constructor Comp.Shared.Mail.Mail()

如果有人能帮助我的话，我已将公司名称替换​​为“Comp”，这会很棒。 谢谢！亲切的问候。
