DatePicker Control Error

I needed to use datepicker control in my WPF application but I couldn't find this control in Toolbox. Then I installed WPFToolKit and added namespace in xaml file code but still it shows following error:
Error 1 The tag 'DatePicker' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'. Line 23 Position 18. F:\Muhammad Anees\codereason_reports_v0.5_alpha\Samples\SimpleReport\EmployeeManager.xaml 23 18 Employee_Manager

Here is my xaml file code:

<Window x:Class="SimpleReport.EmployeeManager"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

IF this is the wpf toolkit from nuget then you call it like: 

 <toolkit:DatePicker Name="blah blah" Margin="0" ect.. > </toolkit:DatePicker>

You may also have to try and clean and build the solution cause I actually got this error before to using the toolkit, but it worked after I rebuilt the solution.

I think you are using WPF Toolkit, you need to use toolkit as you have specified that in the start for WPF toolkit Assembly

<toolkit:DatePicker Height="25" HorizontalAlignment="Left" Margin="42,26,0,0" Name="datePicker1" VerticalAlignment="Top" Width="115" />
