NuGet package manager

Also, you can use the Nuget Package Manager in Visual Studio to install the Pdfium.Net SDK. In this case, run the following command in the Package Manager Console:

PM> Install-Package Pdfium.Net.SDK

NuPack is focused on installing libraries and tools into a Visual Studio solution. It explicitly does not install anything outside of that folder such as User Controls into Toolbox. So you must do it self. Please, see instructions here: "How to add a PdfViewer control to the Toolbox" or see the video below.

Source codes

We provide the source codes for PdfViewer user control and related components. It can be loaded from github: https://github.com/Patagames/
