This document describes assemblies required by web projects that use the functionality of the DevExpress ASP.NET Gauges. Some of the assemblies are essential, while others that provide additional functionality can be optionally deployed, depending on your requirements.


If you use other DevExpress components in your project, using and deploying them should comply with corresponding EULA documents. For more details on licensing information and the redistribution policy of DevExpress, refer to Redistribution and Deployment.

Depending upon the permissions you have on a production server and the amount of web applications that use the same assemblies provided by DevExpress, you can either register the assemblies in the global system assembly cache (GAC) or place them into the Bin folder of your application on the target computer. To learn more about web project deployment techniques, see ASP.NET Deployment Content Map in MSDN.

Required Libraries

Below are the essential libraries required by applications that use the DevExpress ASP.NET Gauges. These libraries are considered to be redistributable under the .NET Controls & Frameworks EULA, and thus can be redistributed legally.




Implements the most basic functionality common to all DevExpress controls. This includes classes for data binding, skinning, printing, exporting, as well as many other auxiliary types and resources.


Contains classes that implement the core functionality of all DevExpress web controls and the functionality of controls from the following components: Data Editors, GridView, Card View, Vertical Grid, Data and Image Navigation, Docking and Popups, Site Navigation and Layout, File Management and Multi-Use Site Controls.


Contains classes that implement the basic functionality for DevExpress printing libraries.


Contains classes that implement the logic for formatting rich text, as well as basic types that provide a public API common to such DevExpress RTF controls as ASP.NET RichEdit, WinForms RichEdit, and WPF RichEdit.

This assembly is also required when using a Rich Edit in-place editor (RepositoryItemRichTextEdit) and/or exporting to DOCX.


Contains common algorithms for drawing gauges in different platforms for XtraGauges and ASPxGauges.


Contains over 150 ready-to-use Gauge presets for the ASPxGauges and XtraGauges Suites.


Contains classes that implement functionality related to the ASP.NET Gauges.

Optional Libraries

The following libraries provide additional functionality for web projects that use the functionality of the DevExpress ASP.NET Gauges.


Redistributable Libraries

The following list summarizes libraries considered redistributable under the .NET Controls & Frameworks EULA.


  • DevExpress.Data.v20.2.dll
  • DevExpress.Web.ASPxGauges.v20.2.dll
  • DevExpress.Web.ASPxThemes.v20.2.dll
  • DevExpress.Web.v20.2.dll
  • DevExpress.XtraGauges.v20.2.Core.dll
  • DevExpress.XtraGauges.v20.2.Presets.dll



By default, all required DevExpress assemblies are located in the "C:\Program Files (x86)\DevExpress 20.2\Components\Bin\Framework\" folder of your development machine after installation.

Non-Redistributable Libraries

Distributing any DevExpress design-time libraries ending with ".Design" is strictly prohibited. It means that you cannot use our installation for a deployment purpose since it includes design libraries that cannot be distributed according to the terms of our EULA.


Please consult the EULA for additional up-to-the-minute information on which libraries, tools and executables are considered redistributable.
