You can via reflection.. but not in any really useful way:
var module = Assembly.LoadFile("path_to_dll.dll").GetModules()[0];
// the first and only module in your assembly
var method = module.GetMethod("PrintMe");
method.Invoke(null,
BindingFlags.Public | BindingFlags.Static,
null,
null,
CultureInfo.CurrentCulture); // Prints "I'm alive!" to console.
