C# BeginInvoke Only Working Inside Visual Studio?

[Yorkiebar14]

Hi,

I'm facing an issue where my code is working inside Visual Studio, but failing when I build the application and run it. I have tried Googling for code alternatives to where I've tracked the bug down to, and I can't find anything that works the way I need it to.

Here is my code:

this.console.addLine("Create Notification invoked: " + mainForm.IsHandleCreated.ToString());
            mainForm.BeginInvoke((MethodInvoker)delegate() {
                this.console.addLine("Started");
                Notification noti = new Notification();
                noti.setQueue(this);
                //noti.setInformation(match);
                noti.test(match);
                this.notifications.Add(noti);
                this.showNext();
                this.console.addLine("Creating notification ID... " + noti.GetHashCode().ToString());
            });

(console.addLine is a custom output method, which works).

So when I run the application inside Visual Studio I get the first line of "Create Notification invoked: True", then I get a line which says "Started" and it all works fine. But if I build the application and run it outside of Visual Studio, I only get the first line "Create Notification invoked: True". I don't get the "Started" line, and it doesn't create the new Notification form instance.

Help is greatly appreciated,
Thanks!

EDIT:
I should probably also mention that 'mainForm' is set to a new Form1 (startup form);
public static Form1 mainForm = new Form1();
