This article describes how DotNetBrowser is supplied and which libraries should be deployed.


DotNetBrowser is supplied in a few dynamic libraries. Few of them are related to DotNetBrowser itself and others to the appropriate Chromium binary files. 

Here's a list of the libraries provided in the distribution package:


AssemblySizeReferencesDescription

DotNetBrowser.Chromium32.dll
DotNetBrowser main DLL for x86 environment. Supports x64 environment.
DotNetBrowser64.dll
~2 MB
DotNetBrowser.Chromium64.dll
DotNetBrowser main DLL for x64 environment. Does not support x86 environment.
DotNetBrowser.Chromium32.dll
~61.7 MB

Chromium x86 binaries. This DLL is a container for the bound Chromium-based engine.
DotNetBrowser.Chromium64.dll
~64.7 MB

Chromium x64 binaries. This DLL is a container for the bound Chromium-based engine.


The libraries you have to deploy are depended on the Windows architecture and your .NET application platform.

  • AnyCPU

DotNetBrowser.dll, DotNetBrowser.Chromium32.dll and DotNetBrowser.Chromium64.dll libraries should be included in your .NET application. For the first time, DotNetBrowser will check the applications architecture and extract/use the appropriate Chromium binaries. On Windows 64-bit DotNetBrowser will extract and use Chromium 64-bit binaries. On Windows 32-bit – Chromium 32-bit binaries.

  • x86

DotNetBrowser32.dll and DotNetBrowser.Chromium32.dll. If it’s a 32-bit .NET application, then Chromium 32-bit binaries will be extracted and used. Chromium 32-bit binaries work well in both Windows 32-bit and 64-bit environments.

  • x64

DotNetBrowser64.dll and DotNetBrowser.Chromium64.dll. If it’s a 64-bit .NET application, then Chromium 64-bit binaries will be extracted and used. If it’s a 32-bit .NET application – an exception will be thrown.


The way to deploy the required libraries is totally up to you.
