| I am trying creating a class dynamically at runtime with
| Activator.CreateInstance(ObjType); where ObjType is retrieved through
|
| foreach (Type tipo in ass.GetTypes())
| {
| ObjType=tipo.GetType();
| tmp=(IPlugin)Activator.CreateInstance(ObjType);
| }

I think your problem is that you are getting the type of System.Type !!

foreach (Type tipo in ass.GetTypes())
{

  // assuming tipo now contains the type that you want to create...

| ObjType=tipo.GetType();

  // ObjType now contains System.Type as that would be the type of tipo.

| tmp=(IPlugin)Activator.CreateInstance(ObjType);
| }

I think you need to remove one line of code like this :

foreach (Type tipo in ass.GetTypes())
{

  tmp=(IPlugin)Activator.CreateInstance(tipo);
}
