Question

i’ve installed silverlight toolkit from codeplex (NuGet didn’t work, feed was empty.. probably working on the project) and after referencing

Microsoft.Phone.Controls.Toolkit

I get the error :

The type or namespace name ‘Toolkit’ does not exist in the namespace
‘Microsoft.Phone.Controls’ (are you missing an assembly reference?)

What could it be?

Answer 1

Because your xmlns is calling it toolbox but the prefix is toolkit.

Change

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

to

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

Or, change your prefix to toolbox. It doesn’t matter what you call it; it just has to be consistent.
