Exception exception from AppDomain.AssemblyLoad

Question

Can someone explain to me why I cannot throw an exception from within the AppDomain.Assembly loading event? For instance:

class Program
{
    static Program()
    {
        AppDomain.CurrentDomain.UnhandledException += (s, a) =>
        {
            Console.WriteLine("Caught exception!");
        };

        AppDomain.CurrentDomain.AssemblyLoad += (s, a) =>
        {
            Console.WriteLine(string.Format("Assembly {0} loaded", a.LoadedAssembly.FullName));

            throw new Exception();

            Console.WriteLine("Should never get here...");
        };
    }

    static void Main(string[] args)
    {
        Console.WriteLine(new ClassLibrary1.Class1().TestString());
        Console.WriteLine();
        Console.WriteLine("Done...");
        Console.ReadLine();
    }
}

When I do this, the output is as follows:

Assembly ClassLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null loaded
TestString
Done...

Can someone explain this behavior to me? Thank.

EDIT To clarify a couple of things:

• The assembly load event runs fine when I expect it to fire. But my exception never throws

• This is a distilled example taken from a larger application. I want to check the assembly after loading it, and if I don’t like it, I want to work quickly ... But my exception doesn’t happen "
