How can I keep a log of NullReferenceException errors that occur in a razor view?

Occasionally a developer will not instantiate a required part of a viewmodel and the corresponding razor view will throw a NullReferenceException error. From there, customErrors redirects to a generic server error 500 view.

I want to log that error in a repository so these incidents can be discovered and fixed. Is there part of the framework that can handle this?

You can use logging frameworks like ELMAH or LOGNet, which are great tools but sometimes you just want to shove it into a database or send a simple email. To manage something like that I have found the best solution is to create a base controller that all of your controllers will inherit from and override the following:

protected override async void OnException(ExceptionContext filterContext)
{
}

Anytime an exception handles in the view or in the controller it will hit here before doing anything. You can still even have other frameworks work with this also.
