UI Frameworks for .NET: The Apple of Discord 2.0

When developing with .NET, picking the right UI framework can quickly turn into a real headache. Between legacy technologies like Windows Forms, newer ones like .NET MAUI or Blazor, and promising challengers such as Uno or Avalonia, it’s not easy to find your way around.
Yet this choice is decisive:  it directly impacts the quality, performance, and longevity of your applications.

That’s exactly why this white paper was created: to help you see things clearly, compare your options, and make the right decision from the start. Inside, we break down the strengths and weaknesses of each framework, their ideal use cases, and their limitations, so you can avoid unpleasant surprises along the way.

You’ll also find a look back at the evolution of .NET UI frameworks. From Silverlight to .NET MAUI, we trace how (and why) some technologies disappeared while others gained traction, and most importantly, where things are heading next.

Finally, we’ve made your life easier with a clear, side-by-side comparison table: at a glance, you’ll identify which framework best fits your needs, whether you’re targeting desktop, web, or mobile, on Windows, Linux, Android, or iOS.

Here’s what you’ll learn:

• Which frameworks to avoid in 2025 (even if they once had their moment of glory)
• Modern alternatives that combine performance, sustainability, and simplicity
• The best options for your targets: Windows, Web, or cross-platform
• Hidden costs, compatible tools, and common technical pitfalls

Whether you’re a developer, tech lead, or architect, this guide will save you valuable time… and more than a few headaches.
