LongListSelector does not exists in the namespace clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit

Question

I'm trying to use the longlistselector from Windows Toolkit in my project but I always have this error. I added the namespace to my xaml and try to restrart visual studio several times. Of course, the toolkit is installed with nuget package manager.

EDIT : I'm on windows phone 8.1

Here is the XAML code:

                </Grid>
            </PivotItem>
            <PivotItem Header="Recherche" Foreground="White">

                </Grid>
            </PivotItem>
        </Pivot>
        <TextBlock Height="92" TextWrapping="Wrap" VerticalAlignment="Top" Width="400" Text="EPIVIDEO" FontSize="32" TextAlignment="Center" FontFamily="Digital Desolation" Foreground="#FF00E8FF"/>
    </Grid>
