When I create a rdlc file(Report) the dialog box : "Website Data Sources" is empty, I can add a typed dataset, but the buisness objects (Classes) I created sometime disappear and sometime shown,
When I click/ remove some references it show and hide.
I would really appriciate some help,
thanks in advance,
It works fine but after a while, it disappears again.
I tried it on several computers(which means it's not a problem of my machine), and tried it on several projects, all behave the same.
