The solution from my blog post (referenced in the OP) was based on an existing solution we were/are using to alter HTTP Response Codes during an error state. So, for us it was a one-line change to pass the Exception to ELMAH. If there’s a better solution, I’d love to know about it too. For … Read more
We needed the ability to log from a console app and a windows service in addition to our ASP.NET site. I used the answer (ErrorLog.GetDefault(null);) which worked well until I needed to email too. So, here is my solution. It handles the log, email, tweet and filtering (both in the config file and in code). … Read more

Pablo Fernandez): Cassini, the development web server used by Visual Studio when you press F5 or click the green «play» button, is x86 only which means … Read more
You can subclass HandleErrorAttribute and override its OnException member (no need to copy) so that it logs the exception with ELMAH and only if the base implementation handles it. The minimal amount of code you need is as follows: using System.Web.Mvc; using Elmah; public class HandleErrorAttribute : System.Web.Mvc.HandleErrorAttribute { public override void OnException(ExceptionContext context) { … Read more
