You could use Reflection to load the assembly into an Assembly object
and to instantiate your type, e.g. (compiled with Gmail):
AssemblyName name = new AssemblyName("myassembly");
// set name's properties as needed
Assembly assembly = null;
try {
assembly = Assembly.Load(name);
}
catch (Exception) { // specialize this if needed
}
IMyObject myObject = null;
if (assembly != null) {
Type myObjectType = assembly.GetType("MyObject1");
myObject =(IMyObject)Activator.CreateInstance(myObjectType);
}
else {
myObject = new MyObject2();
}
(I haven't tried it out, so I might've missed something important. And
you should probably add some error checking as well.)
