the file does not contain any valid add-ins
I'm deveopment my first add in .NET application.
I follow all steps from file: connect_addin_framework_getting_started_guide.pdf
But, in the last step, when I try to add the add-in (login like admin), I browse the dll file, end the system show the message:
"the file does not contain any valid add-ins"
and don't add the add-in.
Thanks a lot
