Debugging constructor exceptions when using assembly.CreateInstance()

I'm working on an app that creates a number of objects with a standard constructor by using assembly.CreateInstance() which all works as expected.

The complication however comes when the constructor raises an exception which is then raised in the calling code as a TargetInvocationException with the InnerException property set. Is there a way to get Visual Studio to debug the exception as it does if I was calling the constructor directly?

I'm thinking of temporarily making it a switch block based on the type name, but this won't help when the objects are in a different (non referenced) assembly.

Sample code:

namespace CreateInstanceTest {
    public static class Program {
        [STAThread]
        public static void Main() {
            Type testType = typeof(TestClass);
            Tes开发者_JAVA百科tClass test = (TestClass)testType.Assembly.CreateInstance(testType.FullName, false, System.Reflection.BindingFlags.CreateInstance, null, new object[] { "value" }, null, null);
        }
    }

    public class TestClass {
        public TestClass(string param) {
            throw new Exception("My exception");
        }
    }
}

Thanks.

For debugging, I ended up using something similar to:

BuildAction action = null; //(BuildAction)actionType.Assembly.CreateInstance(actionType.FullName, true, System.Reflection.BindingFlags.CreateInstance, null, new object[] { subReader, format }, null, null);
switch (actionType.Name) {
case "SetVariable":
    action = new Actions.SetVariable((XmlReader)subReader, format);
    break;
case "DisplayMessage":
    action = new Actions.DisplayMessage((XmlReader)subReader, format);
    break;
}

Which bypasses the dynamic CreateInstance call.
