UI options for Windows Forms?

[finsi]

I need to develop a simple app using .NET and Windows Forms. One requirement I have is build a beautiful GUI. However I find Windows Forms quite limited for this purpose. There are any good libraries NuGet ir anything to improve the capabilities or visual styles of Windows Forms ?
I checked MaterialSkin but still is kinda limited. Help appreciated.

Hi, Finsi,

I would like to note that Telerik UI for WinForms suite offers a great diversity of built-in themes that brings different modern style to your application: https://docs.telerik.com/devtools/winforms/styling-and-appearance/using-default-themes 

We offer a touch optimized theme, MaterialTheme, which provides additional features such as custom fonts, built-in animations and shadows. We also have three other themes that are using the material theme as foundation but have different colors: MaterialBlueGray, MaterialPink, MaterialTeal: https://docs.telerik.com/devtools/winforms/styling-and-appearance/touch-themes 

Once you install the Telerik UI for WinForms suite, you can give the Theme Viewer a try and have a look at the design for all themes that we provide.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
