Explanation/Reference:
Note: Example code with inline lambda expression for the handler:
class Example
{
static void Main()
{
AppDomain.CurrentDomain.FirstChanceException +=
(object source, FirstChanceExceptionEventArgs e) =>
{
Console.WriteLine(“FirstChanceException event raised in {0}: {1}”,
AppDomain.CurrentDomain.FriendlyName, e.Exception.Message);
};
Example with handler defined separately:
static void FirstChanceHandler(object source, FirstChanceExceptionEventArgs e)
{
Console.WriteLine(“FirstChanceException event raised in {0}: {1}”,
AppDomain.CurrentDomain.FriendlyName, e.Exception.Message);
}

To be precise:
public class MyFirstChanceExceptionHandler
{
public static void Handler(object src, FirstChanceExceptionEventArgs e)
{
Console.WriteLine(“Raised in {0} : {1}”, AppDomain.CurrentDomain.FriendlyName, e.Exception.Message);
}
static void Main()
{
AppDomain.CurrentDomain.FirstChanceException += Handler;
}
}
