When using Visual Studio, you can add the DevExtreme libraries to your application using the DevExtreme Web NuGet package. Run the following command in the Package Manager Console to install this package:
Install-Package DevExtreme.Web -Version 19.2.15
You can also use the Manage NuGet Packages dialog to install or update the package.
The DevExtreme Web package contains inseparable DevExtreme scripts. We recommend using the DevExtreme npm package instead if you are developing a modular application.
After installing the NuGet package, you need to link the DevExtreme stylesheets and scripts. Open your index page and add the links to the
<head> tag as shown in the Local Scripts article. Note that the NuGet package contains only dx.viz.js, dx.web.js, and dx.viz-web.js.
