This question is an exact duplicate of:
Earlier today I deployed my project and SSIS packages to my SQL Server, the succesfully showed up in the SSIDB catalog. I encountered an error about a key that I had intended to fix when I got home to continue working the issue. Now when I pull up the same project solution in SSDT (visual studio 2015) I click on the link to launch the last project I was working on. However, now I see absolutely no SSIS Packages and I can't figure out how the hell to get them to appear. The project is still there in SQL Server but apparently has disappeared from my Visual Studio after hitting deploy project. How can I reload my project with my packages that I just pushed to my server?
