Question

我一直在使用Extjs 6进行MVC，当我在visual studio 2015上运行它时效果非常好，但是当我将它部署到Windows 2012 R2中的IIS 8.5时，我得到一个空引用异常。登录后以及页面尝试加载时，会立即发生错误。信息： VersióndeMicrosoft .NET Framework：4.0.30319; VersiónASP.NET：4.6.1055.0 assembly =“System.Web.Mvc，Version = 5.2.3.0 在Windows 2012 R2中 IIS：8.5

谢谢。

Answer 1

出于某种原因：

检查您的代码。

检查Web.config文件是否存在空引用异常。

感谢您的回答，但我在web.config中有这个：
