Only OnConnection fires in Visual Studio add-in

Question

I'm busy with a small, simple add-in, but the process seems massively complicated and badly documented. Right now, the only event that fires in the add-in is OnConnection. The other two I'm trying to handle just don't seem to exist.

    private DTE2 applicationObject;
    private SolutionEvents solutionEvents;

 public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
 {
        applicationObject = (DTE2)application;
     solutionEvents = ((Events2)applicationObject.Events).SolutionEvents;
        solutionEvents.Opened +=new _dispSolutionEvents_OpenedEventHandler(SolutionEvents_Opened);    
 }
    private void SolutionEvents_Opened()
    {
        Debug.WriteLine("Solution loaded: " + applicationObject.Solution.FullName);
    }

Answer 1

Umm, have you tried saving a copy of Events.SolutionEvents locally? I'm guessing that it could 'disappear' if there's no explicit reference to it in your add-in.

This is just a guess though :)
