New Post: Host objects that implement IExpando (IDispatchEx)

Hello,

That's correct; ClearScript doesn't provide dynamic exposure for IReflect/IExpando instances.

Questions:

• What script engine(s) are you using?
• Are these managed objects? Or do you need to expose native COM objects?
  

In any case, this isn't a scenario we've encountered before. If you need to get this working quickly, consider creating a wrapper that implements ClearScript's IPropertyBag or System.Dynamic.IDynamicMetaObjectProvider (or derives from System.Dynamic.DynamicObject).

Good luck!
