Question

I have a problem debugging Invoke() or BeginInvoke() in Visual Studio 2008.

For instance in the code below the debugger breaks on the Invoke() call. I would have liked it to break on Console.WriteLine(p.ToString()); because that is where an exception is thrown. In code as simple as this this is not that much of a problem but it can get really annoying in more complex code. (With BeginIvoke() things even get worse because then the debugger breaks on Application.Run(new Form1());)

Is there any way to make the debugger break at the location of the original exception?

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        Invoke(new Action(MyMethod));
    }

    private void MyMethod()
    {
        object p = null;
        Console.WriteLine(p.ToString());
    }
}

Debug menu > Exceptions > Check the “Thrown” box for any exception you want to break into the debugger at the point it’s thrown.
