How to put a UserControl into Visual Studio toolBox

I had problems getting them to add automatically to the toolbox as in VS2008/2005.

There's actually an option to stop the toolbox auto-populating!

Go to Tools > Options > Windows Forms Designer > General

At the bottom of the list, you'll find Toolbox > AutoToolboxPopulate which on a fresh install defaults to False. Set it true and then rebuild your solution.

Hey presto, the user controls in your solution should be automatically added to the toolbox.

You might have to reload the solution as well.

Right-click on toolbar then click on "choose item" in context menu. A dialog with registered components pops up. in this dialog click "Browse" to select your assembly with the usercontrol you want to use.

PS. This assembly should be registered before.
