Telerik seems to be running a survey about Blazor on their documentation pages and forum, the survey includes a question about which Javascript framework you will be using in the next 12 months and Aurelia is listed.
Anyone using Kendo UI should consider completing the survey and giving Aurelia a little boost
My company already cancelled a large contract with Telerik due to them not creating at least a vanilla JS version of their next controls. We switched to Syncfusion and have not looked back.
I have no experience with Telerik at all. But it’s shocking to hear such things.
In the past (from 2012 to 2015) I have been using DevExpress components for .NET. They also have webcomponents, but I have never used those either.
Currently, since 2018, I am more involved with webdevelopment, but I do not use any commercial 3rd party components at all. I have been developing just in plain vanilla JavaScript and TypeScript for two years now, writing my own HTML Web Components where it fits.
But since I started using Aurelia (since this year), I doubt that I will ever need any of such commercial 3rd party component libraries at all. I do not need them for my current development projects anyway.
