Ext.NET is built on top of Sencha Ext JS, the popular UI framework. This means all our components come with great theming options, allowing your app to fit together seamlessly with any design aesthetic.

No need to have a designer or CSS expert on your team, simply choose a theme and start building great looking, usable interfaces with ease. With Ext.NET, worrying about cross-browser compatibility or user experience issues is a thing of the past.
