Hi Jeffery,

Finally getting back to this now that I have time. In my project, all I have is "Global.asax" without the associated "Global.asax.cs" class.

It's contains:

<%@ Application Inherits="Umbraco.Web.UmbracoApplication" Language="C#" %>

Any idea how I get that .cs class added in and what I need to change the existing Global.asax code to be to link up?

Thanks, Chris

Hi, Chris.

In modern Umbraco apps, you need to create a class that inherits from ApplicationEventHandler.

For example, I made a class called RegisterEvents and put it in an 'Events' folder in the root of my project. In this class, you can override the ApplicationStarting event that Jeffrey mentions in his post. It will look something like this:

public class RegisterEvents : ApplicationEventHandler
{
    protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        ImageProcessingModule.ValidatingRequest += ImageProcessingModule_ValidatingRequest;

        base.ApplicationStarting(umbracoApplication, applicationContext);
    }

    private void ImageProcessingModule_ValidatingRequest(object sender, ImageProcessor.Web.Helpers.ValidatingRequestEventArgs e)
    {
        if (string.IsNullOrWhiteSpace(e.QueryString)) return;

        // When we encounter the s.gif, skip the image processing module to prevent the error
        if (e?.Context?.Request?.FilePath == "/App_Plugins/PerplexMail/s.gif")
        {
            e.Cancel = true;
        }
    }
}
