Iam in searching. But in MSDN they describe about it and say that it is not a direct tool for vb.NET. you have to create a user control through WPF. and then you can use it. but I am in searching a ready tool like others which performs my every work as ToolBar Does.
Even if you find a ready tool you'll have to write code in it, so take that effort and create your own toolBar that will suit your needs.
There's a lot of video tutorial on how to use or design your toolstrip, give it a try. Youtube.com
