Why is ASP.NET MVC Authorize attribute throwing a null reference exception?
- by robertz
I had a working asp.net mvc application running on my local IIS 7 web server, but now I'm getting errors whenever I request a page that requires authorization. I'm using standard forms authentication with asp.net membership. Here's the error:
Stack Trace:
[NullReferenceException: Object reference not set to an instance of an object.]
System.Web.Mvc.AuthorizeAttribute.AuthorizeCore(HttpContextBase httpContext) +31
System.Web.Mvc.AuthorizeAttribute.OnAuthorization(AuthorizationContext filterContext) +38
System.Web.Mvc.ControllerActionInvoker.InvokeAuthorizationFilters(ControllerContext controllerContext, IList`1 filters, ActionDescriptor actionDescriptor) +103
System.Web.Mvc.ControllerActionInvoker.InvokeAction(ControllerContext controllerContext, String actionName) +345...
