Pdf Library for .NET


There are 2 ways to install SelectPdf library:

  • Using a NuGet package (.NET Framework, .NET Core and .NET 5)

  • Downloading assemblies

Installation using Nuget Packages

The easiest way to install SelectPdf is by using a Nuget Package. Create your project, go to Nuget Package Manager and install one of the following packages:

.NET Framework version - AnyCPU (.NET 2.0 and .NET 4.0-4.5) - Select.Pdf:

.NET Framework version - x64 optimized version - Select.Pdf.x64:

.NET Core and .NET 5 version - Windows only (and .NET 4.6.1 and .NET 4.7.2) - Select.Pdf.NetCore:

.NET Core and .NET 5 version with Blink rendering engine - Windows only (and .NET 4.6.1 and .NET 4.7.2)- Select.Pdf.NetCore.Blink:

Note 1: If the x64 version is used, the application needs to target x64 platform and it needs to run in an x64 worker process.

Note 2: The .NET Core version is for .NET Core 2.0 or above through .NET Standard 2.0 (with with .NET Core 2.x, 3.x, .NET 5). Currently it requires a Windows system to run. It does not work on Linux or Mac or Xamarin.

Note 3: Blink rendering engine only works with .NET Core version and with .NET Framework starting with 4.6.1. Blink rendering engine was introduced with SelectPdf v19.1.

Project Setup

To use SelectPdf in a .NET project, a reference needs to be added to Select.Pdf.dll. Two additional files are also required: Select.Html.dep used by the html to pdf converter and Select.Tools.dep used by the pdf to text and pdf to image converter. These files need to be copied into the bin folder of the application, next to Select.Pdf.dll. Alternatively, the path to Select.Html.dep can be specified using the HtmlEngineFullPath property of the GlobalProperties class. The path to Select.Tools.dep can be specified using the PdfToolsFullPath property of the GlobalProperties class.

Important: If any of the properties HtmlEngineFullPath or PdfToolsFullPath of the GlobalProperties class is used, do not forget to include the full file name (Select.Html.dep or Select.Tools.dep) with it.

If Blink rendering engine is needed (only works with the .NET Core version and with .NET Framework 4.6.1 or above), Blink (Chromium) binaries need to be installed. That can be done via Nuget: Alternatively, Blink binaries can be downloaded from SelectPdf website: In this case, the Chromium folder needs to be manually copied to the bin folder of the application.

GAC Installation

If SelectPdf needs to be installed into GAC, the only dll that has to to be added to GAC is Select.Pdf.dll. The related files (Select.Html.dep and Select.Tools.dep) will be automatically copied to GAC as linked resources, so no additional action is needed for them (this is only valid for the .NET Framework 2.0 and 4.0-4.5 versions).
