First of all, let me say everything is fine on VS2012 and VS2013.
On VS2015, the issue started by showing duplicated icons – every icon showed twice. On the Extensions folder, every icon was showing 3 times. That was some 4 or 5 releases ago.
As releases passed by and none solved the issue, I took some actions, every day more serious:
After action 5, no icons show on VS2015. So I repeated steps 1 to 3 above.
To exclude a possible VS2015 issue, I tried to open a VWG and a Windows Forms projects, Reset Toolbox and all is fine.
It’s a common problem when uninstalling and reinstalling toolbox items.
It may be caused by VS being open during reinstallation (could be invisible and in the background – it happens when debugging sometimes). It’s usually a cache problem. We don’t do anything special or different to register the toolbox items. Frank is looking into forcing VS to close when installing.
See this answer from Telerik, it explains how to reset the VS cache:

The problem is solved.
I’m pretty sure I always have VS closed when applying the updates to wisej (but of course I could be wrong) . I’m leaning more towards VS “glitch”. Just taking a look now I have 5 instances of each wisej control in my toolbox.
I found that post too. I also found some other posts that point in the same direction. After the repair of VS2015 if the problem remains I’ll try those steps (repair is taking around 6/7 hours).
Forcing VS to close when installing may help to prevent this problem.
My usual IDE is VS2015. I guess VS2012 is yours. Usually I close VS2015 before installing or removing Wisej. Since the usual IDE is always open, I can’t exclude I forgot to close it on some occasion. I wonder if that’s what caused the issue.
Interesting you should say that because I have the same issue with toolbox duplication in VS2012. I can’t quite put my finger on when or how it happens but the icons do seem to keep duplicating. I’ve also noticed that the chart.js extension is never included in the toolbox after an update. I always have to go and manually add it back in.
