I'm trying to add new application command like 'Save as PDF'

So I created following `DesignerCanvas.Commands.cs` class and added following

        public partial class DesignerCanvas
    {
        public static RoutedCommand SaveAsPDF = new RoutedCommand();

        public DesignerCanvas()
        {
            this.CommandBindings.Add(new CommandBinding(DesignerCanvas.SaveAsPDF, SaveAsPDF_Executed));
        }

        private void SaveAsPDF_Executed(object sender, ExecutedRoutedEventArgs e)
        {
            throw new NotImplementedException();
        }
    } 

then I created 'DesignerCanvas.cs'

    public partial class DesignerCanvas : Canvas
    {
    } 

then Added new Icon to tool bar like this in 'ApplicationToolbar.xaml'

	<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:s="clr-namespace:SampleProject">

					<Button Margin="0,3,0,3" Padding="5" HorizontalContentAlignment="Left"
                            Style="{StaticResource ToolBarButtonBaseStyle}"
                            Command="{x:Static s:DesignerCanvas.SaveAsPDF}"
                            CommandTarget="{Binding ElementName=MyDesigner}">
                        <Button.Content>
                            <Grid>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition/>
                                    <ColumnDefinition />
                                </Grid.ColumnDefinitions>
                                <Image Source="Images/Ungroup.png" Width="16"/>
                                <TextBlock Margin="3" Text="Ungroup" VerticalAlignment="Center" Grid.Column="1"/>
                            </Grid>
                        </Button.Content>

     </ResourceDictionary> 

but here I'm getting this error

The name "DesignerCanvas" does not exist in the namespace "clr-namespace:SampleProject".

I implemented following method to Save canvas to PDF ?

        private void SaveAsPDF_Executed(object sender, ExecutedRoutedEventArgs e)
        {
            SaveFileDialog saveDlg = new SaveFileDialog();
            saveDlg.Filter = "PDF files|*.pdf";
            if (saveDlg.ShowDialog() == true)
            {
                flowchart.SaveToXml(saveDlg.FileName);
                MindFusion.Diagramming.Export.PdfExporter pdfExp = new MindFusion.Diagramming.Export.PdfExporter();
                pdfExp.Export(diagramview.Diagram, saveDlg.FileName);
            }
        } 

above method I refreed from mindfusion documentation page

http://www.mindfusion.eu/onlinehelp/flowchartnet/Diagram_Exporting.htm

but here I'm having following errors

Error 1

'Diagram' does not contain a definition for 'Diagram' and no extension method 'Diagram' accepting a first argument of type 'Diagram' could be found

Error 2

The type or namespace name 'Export' does not exist in the namespace 'MindFusion.Diagramming'

but for this(2nd error) I already installed `MindFusion.Diagramming.Wpf` and gave namespace like this

`using MindFusion.Diagramming.Wpf;`

once I add I'm having following compile time errors

The type or namespace name 'PdfExporter' could not be found
The type or namespace name 'Pdf' does not exist in the namespace 'MindFusion'

I found mindfusion.pdf.dll from below link

http://api.256file.com/mindfusion.pdf.dll/en-download-124273.html

once after add that
'The type or namespace name 'Pdf' does not exist in the namespace 'MindFusion' this error goes away

but I unable to solve below error

'The type or namespace name 'PdfExporter' could not be found'

can you give the exact 'MindFusion.Diagramming.Wpf.PdfExport.dll' as attachment here , because I cant find though I installed Nuget package like this 'Install-Package MindFusion.Diagramming.Wpf'

I copied the `MindFusion.Diagramming.Wpf.PdfExport.dll` from my following location

`Project_Location\packages\MindFusion.Diagramming.Wpf.3.4.2\lib\net40`

then I gave referred following namespace

`using MindFusion.Diagramming.Wpf.Export;`

but then Still I'm having following compile time errors
