I installed the WPToolkit through NuGet and it was successful, but it wasn't add into project's solutions, that's why i can't add in the xaml
xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
<toolkit:AutoCompleteBox...
*The name "AutoCompleteBox" does not exist in the namespace "clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit". *
So what can i do?
I am using:
Microsoft Visual Studio Ultimate 2013
Version 12.0.30501.00 Update 2
Microsoft .NET Framework
Version 4.5.51641
Thx, Robertoq
