Third Party UI Controls List for Windows Store Apps

Hello All,

I saw a list of third party UI controls and toolkits providers for windows store apps on microsoft website or msdn. but could not find it again despite i searched for many days, even checked my history.

Please if any one could help my find that list again. i am developing app for windows store and i saw a few toolkits in that list that may help me.

this is not about the "nuget packages"

Thanks
