How to handle a rendering Exception in WPF (Windows Presentation Framework)

Question

Randomly my system causes this Exception (which I only see because of the logs left in Windows events). It’s an app that runs around 24 hours a day every day. When error occurs, the screen freezes and if I click anything, the program closes with Windows error message.

I already implemented a memory management with GC but apparently this is not the problem.

The point in question is that I can not find where the problem is, since I debugged the whole project, made unitary tests and everything goes perfectly, besides for my understanding, these classes are of the Framework itself . NET, more specifically the rendering part.

Every time it occurs, although it is difficult to occur, it is the same Exception, and I do not know how to treat it.

How can I identify the source of this problem or treat this Exception? If there was a way to just treat Exception so the application wouldn’t crash it would already help.

Speak Renan, if I tell you that I spent the day yesterday with this same problem heheheh.

Well what I got was to use this:

AppDomain.CurrentDomain.UnhandledException += (sender, e) => MessageBox.Show(e.ExceptionObject.ToString());

In the Mainwindow of my application and then yes go treating every problem, see if it helps you.
