Configure Toolbox using pkgdef file

Hi Team,

We have used the below process to configure the custom controls in Visual Studio Toolbox.

-         Creating theToolboxControlsInstaller  key under the below registry path

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\14.0

-         Under the keyToolboxControlsInstaller, our components entry will be display like below

As per the below forum, we can configure the custom controls in Visual Studio toolbox using thepkgdef file.

Now our question is,

1. How to configure the custom control toolbox using pkgdef file ?
2. How to use the pkgdef file and how can we update our assembly entry in pkgdef file ?
