Integrating PSPDFKit Manually

To include PSPDFKit in your app, you can use either the NuGet package or install the PSPDFKit for Windows.vsix Visual Studio Extension — installation steps are outlined below. Learn more about PSPDFKit for Windows in our announcement blog post and on our SDK product page.


  • Windows 10

  • Visual Studio 2017

  • A UWP-based application

  • The PSPDFKit NuGet Package or PSPDFKit for Windows.vsix Visual Studio Extension

If you encounter any problems during the integration, please let us know.

Catalog App

The SDK comes with an example application called the Catalog app. It contains many useful examples for exploring the different features of PSPDFKit and getting started quickly. You can find the app in the Example folder of the SDK ZIP file. The SDK ZIP file can be downloaded from the customer portal or you can request an evaluation license of PSPDFKit.

Building the Catalog App

To build the Catalog app, simply open the solution in Visual Studio, choose the solution platform x86 or x64, build, and run. Note that building and running for ARM requires an ARM-based device.

Basic Integration with Your Own App

Download the SDK ZIP file and unpack it wherever appropriate.

Open Visual Studio and create a new blank UWP app in, for example, C#, with the Project Wizard.

Open package.appxmanifest, which you will see near the bottom of your Solution Explorer.

The rightmost tab, Packaging, has a field called Package name.

It is essential that your package name matches the bundle ID of your license, except for when using a trial license (in which case, it does not matter).

To add PSPDFKit to your application, you can use the NuGet package provided via or in in the SDK ZIP file under the nuget folder, or you can install the SDK as a Visual Studio Extension.

We recommend using the NuGet package, as this does not require a systemwide install of the extension, makes version tracking easier, and simplifies server-based build processes.

To reference the SDK from a NuGet package, please follow this guide.

To reference the SDK from a VSIX, please follow this guide.

In the Solution Explorer, open the file App.xaml.

Add your license key as a String value in the application’s resources:


+   <Application.Resources>
+       <ResourceDictionary>
+           <ResourceDictionary.MergedDictionaries>
+               <ResourceDictionary>
+                   <x:String x:Key="PSPDFKitLicense">YOUR_LICENSE_KEY_GOES_HERE</x:String>
+               </ResourceDictionary>
+           </ResourceDictionary.MergedDictionaries>
+       </ResourceDictionary>
+   </Application.Resources>


Open the main page XAML and paste the following XML as a child of the <Grid> element:

    <RowDefinition Height="*"/>
    <RowDefinition Height="52"/>
<ui:PdfView Grid.Row="0" Name="PdfView" License="{StaticResource PSPDFKitLicense}" />
<Button IsEnabled="False" Content="Open PDF" HorizontalAlignment="Left" Margin="10" Grid.Row="1" Name="Button_OpenPDF" Click="Button_OpenPDF_Click"/>

You’ll see a green line under ui:PdfView. If you hover over it, you will be given the option for potential fixes. Click on this, and Visual Studio will suggest that you include the missing namespace, which you should do. It will then add the following namespace to <Page>:


Open the MainPage.xaml.cs file, add a delegate handler to PdfView.InitializationCompletedHandler in the constructor, and add the button’s click handler function:

public MainPage()

    // This handler is invoked once the `PdfView` has been initialized, and then the `PdfView.Controller` can be used.
    PdfView.InitializationCompletedHandler += delegate(PdfView sender, Document args)
        // Now that the `PdfView` is ready, enable the button for opening a file.
        Button_OpenPDF.IsEnabled = true;

private async void Button_OpenPDF_Click(object sender, RoutedEventArgs e)
    var picker = new Windows.Storage.Pickers.FileOpenPicker();
    picker.ViewMode = Windows.Storage.Pickers.PickerViewMode.Thumbnail;
    picker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.DocumentsLibrary;

    var file = await picker.PickSingleFileAsync();
    if (file != null)
      var document = DocumentSource.CreateFromStorageFile(file);
      await PdfView.Controller.ShowDocumentAsync(document);

Note that you must wait for initialization of the PdfView to be complete before using PdfView.Controller.

In the Build toolbar, choose Debug and x86 or x64 — whichever you prefer.

Then in the menu, select Build > Build Solution.

The solution should build without complaint.

Start the application, and you should be able to open a PDF by clicking on the Open button.

React Native for Windows UWP Support

PSPDFKit for Windows UWP comes with optional support for React Native. This makes it very easy to add PDF support to your React Native Windows app. See our open source GitHub repository for details on how to integrate.

Support for .NET, WPF (Windows Presentation Foundation), and Xamarin

There’s ongoing work by Microsoft to allow integrating UWP controls in WPF apps. We also have a Xamarin wrapper for UWP, and you can check out our Xamarin guide for more information.

Support for Windows 7/Windows 8.1

For companies that still need to support legacy Windows, we offer CEF as a replacement. This has a slightly higher performance impact (around 20–30 percent slower), but otherwise, it is functionally equivalent; it just needs more direct interaction with JavaScript.

Mainstream support for Windows 7 ended on 13 January 2015, and mainstream support for Windows 8.1 ended on 9 January 2018. However, Microsoft will still offer paid extended support until January 2020/2023, respectively.
