I didn't see this issue posted yet but when I installed 11.2 Ultimate, it created multiple instances of each control w/in the Visual Studio 2011 Toolboxes. I can't tell if it is duplicating them each time I open Visual Studio 2011 or not but here is a video of my toolbox for the 11.2 4x Controls & Reporting. Please let me know if you want me to try anything or want any other details. Oh, I have also removed the Toolboxes and re-installed w/ the same results. It also does the same for the 11.2 2x Controls.
I have just verified that each time I open Visual Studio and work on a project it is duplicating each control w/in the Toolbox.
Hello ,
I have installed Infragistics 11.2 on my machine and I have created a toolbox for CLR4 and CLR2, everything was fine. My OS is Win7 SP1, my Visual Studio is 2010 SP1. However I have researched about your issue in the web and I had discovered that other people have a similar issue with duplicating controls in their toolboxes, and not only with Infragistics Components:
