The Top C# .NET UI Controls

When you're choosing UI controls for C# .NET development, there are many things you should consider. You're not just looking for a one-size-fits-all solution. You want a toolkit that's packed with features, versatile enough to handle any project you throw at it, and one that will hold up over time as technologies evolve.

Let’s take a close look at ComponentOne, the oldest .NET UI control toolkit, and see how it stacks up against other big names like DevExpress, Telerik, Infragistics, and SyncFusion. We'll cover key UI controls, platform compatibility, support, and pricing to see where each toolkit provider stands.

ComponentOne

ComponentOne (sold by MESCIUS) supports the latest .NET technologies in addition to supporting older platforms. The most comprehensive plan, ComponentOne Studio Enterprise, is priced at $1495 per developer per year. Priority Support can be added on for $400 per license if needed.

This plan includes full access to all current .NET platforms, data service components, JavaScript components, and high-priority support. It’s the best choice if you plan to work across multiple .NET platforms.

In addition to the latest version of .NET, ComponentOne goes back pretty far to support older versions of .NET as you can still access .NET 4.0. Plus, they offer hundreds of C# samples to help you quickly learn and implement features. Modeled after standard .NET controls, you can easily customize the ComponentOne controls, add themes for your entire application, and update the libraries with NuGet, which makes development straightforward and hassle-free.

ComponentOne covers all your bases with support for a wide range of .NET platforms so that you can build apps for just about any environment. It's the only competitor still supporting legacy applications with ActiveX, though they only offer the existing controls without updates. They also provide a unique suite of data service libraries, making it easier to handle large data sets and connect to cloud data sources and CRMs.  Below is a look at the platforms you can work with:

• WinForms
• WPF
• WinUI
• UWP
• ActiveX
• ASP.NET MVC
• ASP.NET Core MVC
• ASP.NET Web Forms
• Blazor
• Web API
• .NET MAUI
• Xamarin
• .NET Data Services
