I added a http connection manager to my SSIS project, did some additional work, then closed the IDE.
When I opened the IDE (VS 2010 10.0.40219.1 SP1 REL), the http connection manager had vanished. When I examined the project's folder in Explorer, the .conmgr file is present.
Why is this occurring? What do I need to get it to load?
I could not replicate the issue in this instance. Sometimes I did noted similar erratic behavior in VS while working with TFS.
The easiest way to add it back is:
Right click on the Project in the solution explorer -> Add -> Existing Item and Choose the .conmgr file.
