Question

My company is starting a major greenfield development project using DevExpress WPF controls. I just read this critical review of their WPF controls:

Answer 1

I have used Syncfusion, Ingragistics, Telerik as well as various smaller libraries and DevExpress is my platform of choice. I find them to be not only super supportive of WPF and MVVM but their tech support has been phenomenal. I actually was mid project in a multi-million dollar project using Syncfusion WPF and found so many bugs in the library that my customer was close to pulling the plug. I switched mid stream to DevEx and they save my bacon. Their controls always seem the most up to date and incorporating the latest trends. I wish they did more Xamarin stuff and some of the other things that Syncfusion does but I would rather have less stuff that actually works than a wide array of stuff that doesn't.
