Thanks a lot Dale.
I have a similar configuration in project settings, the is: Active(debug 64). please have a look the images attached.
Packing is the rhino plugin command and packinginterface is a project in WPF. When the plug-in is executed, the wpf window is called, the data is processed and son on. Then I use rhino to display the geometry. the code works well. The big problem is I cannot inspect the classes and variables. Because VS community 2015 close Rhino every time I try to inspect a variable.
Since the project it not so big right now, I will creates a new rhino project and an new wpf to test everything again.
I also open a threat in VS forum.
thanks in advance
