Hi Tomas,

No success so far, all variants produce the same exception:
"InvalidOperationException: Empty scope has no global scope." ???

I tried following variants:

  Engine.Operations.InvokeMember(null, "require", 
PathProvider.MapPath(path));
  Engine.Operations.InvokeMember(Context, "require", 
PathProvider.MapPath(path));
  Engine.Operations.InvokeMember(Context.TopGlobalScope, "require", 
PathProvider.MapPath(path))
  Engine.Operations.InvokeMember(Engine, "require", 
PathProvider.MapPath(path))
  Engine.Operations.InvokeMember(Engine.Runtime.Globals, "require", 
PathProvider.MapPath(path))
  Engine.Operations.InvokeMember(Engine.GetScope(null), "require", 
PathProvider.MapPath(path))

with:

  Engine = Ruby.GetEngine(Runtime);
  Context = Ruby.GetExecutionContext(Engine);
  CurrentScope = Engine.CreateScope();
  Operations = Engine.CreateOperations();

Any ideas what's wrong?

Hope for some help, Immo
