Why is Response.StatusCode set to 200 when Application_Error() is invoked?

Question

In my MVC application I sometimes have unhandled exceptions and Application_Error() handler invoked.

The problem is if I access Response.StatusCode inside Application_Error() it happens to be 200 although there was an unhandled exception. I'd rather expect 500.

Why is it 200 although there was an unhandled exception?

inside Application_Error() you may do this:

        var lastError = Server.GetLastError();

        var statusCode = 500;
        var httpException = lastError as HttpException;
        if (httpException != null)
            statusCode = httpException.GetHttpCode();
