Host WPF Control in Window Form

1. Add reference of the PresentationCore , PresentationFramework,WindowsFormsIntegration,IO your window Application's references folder.

2 Add following reference sto your code behind file.
using WPFControls = System.Windows.Controls;
using System.Windows.Forms.Integration;
using System.Windows.Markup;
WHERE,
System.Windows.Markup contains XamlReader file which is used to read the XAML file you have create for adding component.
System.Windows.Forms.Integration is used to host a WPF control .

3. addionally, you have to create a .xaml file in which you have place the code to create a control using WPF,and also you have to add this file to your project.
e.g here is the sample code for button.xaml file
<Button
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
VerticalAlignment="Bottom"
Grid.Column="0"
Grid.ColumnSpan="1"
Grid.Row="0"
Grid.RowSpan="1"
Margin="19,0,139,18.5" Name="button1"
Foreground="black" mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" d:DesignHeight="34" d:DesignWidth="127">
    <Button.Background>
        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
            <GradientStop Color="#FFF0F0F0" Offset="0" />
            <GradientStop Color="#FFF8F2F2" Offset="0.553" />
            <GradientStop Color="#FF9E9A9A" Offset="1" />
            <GradientStop Color="White" Offset="0.65" />
            <GradientStop Color="#FE97AFE7" Offset="0.106" />
        </LinearGradientBrush>
    </Button.Background>
    <Button.Effect>
            <DropShadowEffect ShadowDepth="1" Color="green" BlurRadius="8"/>
        </Button.Effect>

4. Copy the following mention code under under a button 's Click event on your Win form .
  FileStream xamlFile = null;
                        using (xamlFile = new FileStream(FileName, FileMode.Open, FileAccess.Read))
            {
                //parsing the xaml file into object
                object xamlObject = XamlReader.Load(xamlFile);
                if (xamlObject.GetType() == typeof(WPFControls.Button))
                {
                    wpfButton = (WPFControls.Button)xamlObject;
//allocate memory to th Element Host
                    ctrlHost = new ElementHost();
                    ctrlHost.Dock = DockStyle.Fill;
//add host to the parent
                    panel1.Controls.Add(ctrlHost);
