I created 9 add-ins in a project in VS 2008. And I builded project so VS created a .dll file. Using this way
Tools -> Add-in -> Add-in Manager -> Browse -> (choose .dll which I created at VS 2008)
when I add add-in's .dll file to SAS Enterprise Guide 4.3, it works perfectly, EG 4.1 recognizes all of add-ins in .dll. But when I add add-in's .dll file to SAS Enterprise Guide 5.1, SAS EG 5.1 shows only 8 add-ins. It doesn't recognize one of them.
How can I solve this problem?
