Export Attribute on method not working

Elements Oxygene
1

Hi,

I am trying to implement Caliburn Micro into a test application and all was going well until I reached a point where you need to decorate a method with an attribute. Here is the website that I am using as a reference :- http://www.mindscapehq.com/blog/index.php/2012/2/1/caliburn-micro-part-4-the-event-aggregator/

The attribute in questions is :- [Export(typeof(AppViewModel))]

The compiler complains with the following

 Error    2    (E62) Type mismatch, cannot assign "System.ComponentModel.Composition.Primitives.Export" to "Attribute"    E:\[Oxygene]\[Tests]\CaliburnMicroTest\ViewModels\ShellViewModel.pas    13    4    CaliburnMicroTest

Am I doing something wrong or does Oxygene not support decorating methods this way ? If so, then how do I get it to work with Caliburn Micro ?

Regards
Anthoni

Hello Anthoni,
look at your uses or use the full attribute name, using the namespace:
the ExportAttribute class is defined in System.ComponentModel.Composition, not in System.ComponentModel.Composition.Primitives.

Thank you so much :smiley:
It now works perfectly.

Caliburn.Micro is now integrated into my test application.
