How do I find what is causing an entity to be modified (in XAF)?


I need to find what code is causing an entity to be modified. In my .Net Core Winforms XAF EF app When I go into a detail view and click close I get a message asking me to save, even though I have not edited anything.

I added a listener to my ViewController as follows

    private void ObjectSpace_ModifiedChanged(object sender, System.EventArgs e)
    {
        var os = sender as EFCoreObjectSpace;
        foreach (var mo in os.ModifiedObjects)
        {
            Debug.Print(mo.ToString()); // break point
            // debugger shows that mo is of type Castle.Proxies.JobExtProxy
        }
    }

At run time, at the break point I see the following call stack.

I have changed the framework to net6.0-windows so I am unsure if that matters.
