This "answer" is an elaboration for Jon's answer. (Marking CW)

For the record, DynamicInvoke is a bit slow. To illustrate this, consider the following program:

void Main()
{
    Func myFunc = i => i.ToString();
    myFunc.DynamicInvoke(1);   // Invoke once so initial run costs are not considered
    myFunc(1);

    Stopwatch stopwatch = new Stopwatch();

    stopwatch.Start();
    for (int i = 0; i < 1000000; i++)
        myFunc.DynamicInvoke(1);
    stopwatch.Stop();

    var elapsed = stopwatch.Elapsed;

    stopwatch.Restart();
    for (int i = 0; i < 1000000; i++)
        myFunc(1);
    stopwatch.Stop();

    var elapsed2 = stopwatch.Elapsed;

    Console.WriteLine("DynamicInvoke: " + elapsed);
    Console.WriteLine("Direct Invocation: " + elapsed2);
}

Prints out:

DynamicInvoke: 00:00:03.1959900
Direct Invocation: 00:00:00.0735220

Which means that DynamicInvoke (in this simple case) is 42 times slower than direct invocation.
