Windows Phone AutoCompleteBox was not found

Question

My XAML file errors when I try <toolkit:AutoCompleteBox> although I added a reference to the Microsoft.Phone.Controls.Toolkit.dll file. Everywhere I have read says this should work.

Answer 1

3 steps to make this work:

1. First reference the assembly in your project

2. Secondly reference the namespace in your xaml file

3. Finally point to the control you want to use in the namespace

I guess that you're missing the second step:

xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
