There are multiple implementations of IDispatch available for you to expose dual interfaces and dispinterfaces to COM. Attach this attribute to a class or an assembly to specify which IDispatch implementation to use. If you apply this attribute to an assembly, it applies to all classes within that assembly. For a list of available IDispatch implementations, see IDispatchImplType.

public sealed class IDispatchImplAttribute : Attribute {
// Public Constructors
   public IDispatchImplAttribute(IDispatchImplType implType);
   public IDispatchImplAttribute(short implType);
// Public Instance Properties
   public IDispatchImplType Value{get; }
}
