Ninject 尚未为 Web 应用程序注册内核

Question

我刚刚继承了一个用 Framework 4.8 编写的程序。这是一个 asp.net 应用程序。当我们尝试点击我们网站上的登录页面时，我们收到此错误：

我已经尝试重置应用程序池、重新部署站点，甚至重新启动整个服务器，但它仍然失败。我没有使用 Ninject 的经验，我对问题或解决方案一无所知。托管此页面的主站点正在运行，只是此页面出现故障。如果需要，我可以提供代码，但我不知道此时有什么用。该站点正在使用 Ninject 3.2.0

Answer 1

这实际上是 web.config 文件中的连接字符串的问题。一旦我们将它指向正确的位置，它就会再次开始工作。它与 Ninject 无关，那是错误被捕获和抛出的地方，这反过来又使我们摆脱了实际问题。

Ninject 尚未为 Web 应用程序注册内核

Ninject no kernel has been registered for the web application

asp.net

ninject.web.mvc
