Uninstalling doesn't clean the toolbox
Question / Problem
I have uninstalled ShellBrowser components, but the toolbox keeps showing one or more ShellBrowser controls.
Answer / Solution
Probably there was no problem with removing the ShellBrowser files.
Instead Visual Studio sometimes has a problem updating the toolbox from the its cache.
To clear the situation, you can just manually delete remaining components form the toolbox via the context menu (> Delete).
In persistent cases you can choose "Reset Toolbox" to force Visual Studio to update the toolbox.
