I was a big supporter of what the Ext.net engineers do, and in a way I still do. Their tech is very professional and stable.
I stopped using them right after the price hike. IMHO, it is overpriced. Since I can get most of the same stuff done with other frameworks and mostly for free.
This looks identical to the Sencha products [0]. Especially, their ExtJs framework [1].
Both the name and even their examples [2] look practically like copies. Although, ExtJs does seem more fleshed out and way more full fledged [3]. They seem to have bindings with other frameworks too, like React and Angular [4].
The ExtJs framework started as an open source project ages ago. Is this some kind of a fork from then?
Ext.NET includes Ext JS (currently, v7.1.0) as its client-side component UI. The new Ext.NET 7.0 release provides 100% coverage of all Sencha Ext JS components to use in ASP.NET Core apps, such as Razor Pages or MVC.
I find providing official titles for things including words such as "legacy", "modern", and "classic" is a little folly since whatever you call "modern" becomes legacy or classic sooner than you might imagine.

Nevertheless, their work on https://bridge.net/ is awesome.
