We are making progress in getting one of our clients to upgrade to GP 2013 R2. They are using GP 10 and the first steps was to upgrade their workstations from XP to W7. We have several VS add-ons and in those add-ons was a lookup screen. Since the upgrade of the workstations the lookup screens only work the first time they are called. After that they must be closed and reopened before they will return values. My first thought was the version of Dot Net so I rebuild them using Dot Net 3.5 but that did not help. So now I am thinking of using VS 2013 as opposed to VS 2008 to build these add-ons. My question is will the VS Toolkit for GP 10 be compatible with VS 2013?
