Configuring windows phone tool box with custom controls while installing our product

Hi,

Is there a way to configure the windows phone toolbox with our custom controls during installation in visual studio 2012 or 2013 ?

made registry entry in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\11.0\ToolboxControlsInstaller\, but no use

already put a registry entry in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SDKs\WindowsPhone\v8.0\AssemblyFoldersEx\ this is also not working.

Can anyone please come up with a solution for this ?

Thanks in Advance !!

Regards,
