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


If you use any DevExpress components in your project, their use and deployment should comply with the corresponding EULA documents. For more details on licensing information and the redistribution policy of DevExpress, refer to the following topic: Redistribution and Deployment.

Depending on the production server's permissions and the number of web applications that use the same DevExpress assemblies, you can either register the assemblies in the Global Assembly Cache (GAC) or place them in the Bin folder of your application on the target computer. To learn more about web project deployment techniques, see the following MSDN topic: ASP.NET Deployment Content Map.

Required Libraries

Below are the essential libraries required by applications that use the DevExpress Data Editors.

Assembly Description
DevExpress.Data.v20.2.dll 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.
DevExpress.Web.v20.2.dll 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.

Optional Libraries

The following libraries add functionality to web projects that use DevExpress Data Editors.


  • DevExpress Themes

    If you use any DevExpress Theme, you should deploy the following assembly.




    Contains classes that implement a set of predefined DevExpress themes for DevExpress web controls. See the following topic to learn more: ASPxThemes Assembly.

  • Localization

    If you localize editors using the satellite resource assemblies, you need to deploy the corresponding assemblies. See the following topic to learn more: Satellite Resource Assemblies.

Redistributable Libraries

For a complete list of libraries that are considered redistributable under your registered product's EULA, refer to the following help topic: Redistributable Assemblies (ASP.NET and MVC Deployment).


All 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

Distribution of any DevExpress design-time libraries ending with ".Design" is strictly prohibited. This means that you cannot use our installation for deployment purposes 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.
