I am struggling to use their products… I am struggling to use their products with community licence. Almost every product have problems. Desktop widgeds not properly work at Visual Studio. It messing up all project. Asp controls even basic project not properly setup. Microsoft's standart controls far more nice.

Dynamic Company, Syncfusion I think WinUI is not that popular framework yet. Syncfusion already prepared the best WinUI framework. I chose WinUI for legacy c++ libraries use in .NET framework. I am new to WinUI and there were not many articles I can refer to about WinUI. Syncfusion provides awesome WinUI Controls include beautiful Chart libraries and Grid control. especially Charts with animation is really good. I also like your active support too. Syncfusion contacted me first and asked if I have questions. so I replied with some questions about WinUI Controls. Then I could get the solution quickly. I also saw many other frameworks products. it makes me think of that Syncfusion is very dynamic company and I can get the best help from Syncfusion products in future too.

They went the extra 20 miles to support us We were converting from a graphic library that has not been supported for quite a few years to SyncFusion. Our application requires continuous graphing of high volumes of data in a multi-threaded application. SyncFusion support provided tremendous support to get a solution that would support our needs. They were very patient when I was confused and just did what it took to get this working. What they had to do was not trivial but they managed to get it working. I am VERY impressed.

Excellent Support From other reviews, they seem hit-and-miss, but my experience is excellent. One query I had on the forums was down to the way I was using a control, and another query is a genuine bug report. They got back to me within 24h and are letting me know the bugfix progress. I can't ask for more - especially as I'm only on the community licence.

Untested controls I have been using some of their controls for Xamarin Forms for 5+ years now. My honest opinion is that their controls are highly untested. So if you are aiming for a more complex use than the shown in guide, you are going to find out some important bugs. I can say I found problems with almost all of controls I used. Some problems are just easy to solve (elements of style customization being ignored). Some other are just making the whole control unusable. For instance, SfChat has an obligatory behaviour of starting the listView on the first message and automatically scroll till last one. Super cool when you have 20 messages. UNUSABLE in real cases where you have 1500 messages as you would just stay staring at the screen scrolling by inself for 30 seconds without even being able to interact with the control. If you just want the plain control without any type of customization, it definitely saves you some implementation time.
