System Requirements (ASP.NET WebForms)

This document describes the system requirements to install and use DevExpress ASP.NET WebForms Components v19.1 on a development machine.

Expanded .NET Framework

DevExpress ASP.NET WebForms controls and MVC extensions support the following .NET Framework versions.

DevExpress Version .NET 2.0 .NET 3.5 .NET 4.0 .NET 4.5 .NET 4.5.2 .NET 4.6 .NET 4.7 .NET 4.8
v19.1 (current)
All Versions

If you require a previous version of a DevExpress product, log in to the Download Manager page on the DevExpress website.

Expanded IDE

DevExpress ASP.NET controls support the following Visual Studio versions.

DevExpress Version Visual Studio 2005 Visual Studio 2008 Visual Studio 2010 Visual Studio 2012 Visual Studio 2013 Visual Studio 2015 Visual Studio 2017 Visual Studio 2019
v19.1 (current) * *
All Versions
v18.2.7-v19.1 * *
v18.1.11-v19.1.5 * *

* Starting with version 18.2, DevExpress source code targets C# 6.0. You can still use our pre-compiled assemblies in Visual Studio 2012 and 2013. However, it is not possible to recompile DevExpress source code in these Visual Studio versions.

Visual Studio Express editions may not support some design-time features of DevExpress ASP.NET controls.

Expanded SQL Server

To run the DevExpress ASP.NET MVC Extensions demos locally, one of the following versions of Microsoft SQL must be installed.

  • Microsoft SQL Server 2005 Express Edition (SP3)
  • Microsoft SQL Server 2008 Express Edition (SP1)
  • Microsoft SQL Server 2012 Express
  • Microsoft SQL Server 2012 Express LocalDB
  • Microsoft SQL Server 2014
  • Microsoft SQL Server 2016

Microsoft SQL Server is required because DevExpress demos use locally deployed .mdf files as data sources.


If you are using a custom named instance for your installation of Microsoft SQL Server Express, you will need to browse the web.config files in the demos for connectionString parameter entries, and replace any occurrence of the default instance name ("SQLEXPRESS") with your custom instance name.

Starting with version 13.2, for most popular database engines, the DevExpress .NET Demo Center automatically recognizes the database engines available on the machine. When launching a demo that requires SQL Server from the Demo Center, it will automatically locate available DBMS instances in the following order.

  2. (localdb)\vX
  3. (local)

When opening a demo project directly in Visual Studio, it is possible to adjust the connection strings based on the development environment. Refer to the KA18667 - How to configure SQL Server for demo databases article to learn more.
