jQuery
DevExpress ASP.NET MVC extensions support jQuery version 3.x.
Note
Microsoft .NET Framework 4 and MVC 3 must be installed to run DevExpress MVC demos. If you use MVC 4, you will need to modify the DevExpress MVC demo project slightly, as described in the following article: Upgrading an ASP.NET MVC 3 Project to ASP.NET MVC 4.
Use one of the following IDEs to develop MVC applications with DevExpress ASP.NET MVC extensions.
| Visual Studio version | ASP.NET MVC 3 | ASP.NET MVC 4 | ASP.NET MVC 5 |
|---|---|---|---|
| Microsoft Visual Studio 2019 | |||
| Microsoft Visual Studio 2017 | |||
| Microsoft Visual Studio 2015 | |||
| Microsoft Visual Studio Express 2013 | |||
| Microsoft Visual Studio 2013 | |||
| Microsoft Visual Studio Express 2012 | |||
| Microsoft Visual Studio 2012 | |||
| Microsoft Visual Web Developer 2010 Express SP1 | |||
| Microsoft Visual Studio 2010 SP1 |
| 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 |
|---|---|---|---|---|---|---|---|---|
| v20.1 (current) | * | * | ||||||

Note
* 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.
To run DevExpress ASP.NET MVC extensions demos locally, one of the following versions of Microsoft SQL must be installed.
Microsoft SQL Server is required because DevExpress demos use locally deployed .mdf files as data sources.
Note
If you are using a custom named instance 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 available database engines on the machine. When launching a particular demo that requires SQL Server from the Demo Center, it automatically locates available DBMS instances in the following order:
When opening demo projects directly in Visual Studio, it is possible to adjust connection strings based on the development environment. Refer to the KA18667 - How to configure SQL Server for demo databases article to learn more.

When deploying to IIS, change the default application pool to .NET 4. Refer to the following article to learn more: ASP.NET Web Deployment using Visual Studio: Deploying to Test.
See the following topic for a list of assemblies required by web projects that use DevExpress ASP.NET MVC extension functionality: Deployment - MVC Extensions.
