We’re excited to introduce two brand-new, modern themes for Wisej.NET: FluentUI Light and FluentUI Dark. Inspired by Microsoft’s Fluent Design System, these themes bring a sleek, professional, and highly legible look to your Wisej.NET applications — whether you prefer bright clarity or deep contrast.

A Modern Take on UI Styling
FluentUI Light and Dark are designed to provide a clean and consistent user experience across your applications. With balanced spacing, refined colors, and subtle animations, these themes make interfaces both beautiful and functional — adapting effortlessly to different environments and user preference
Theme Highlights
FluentUI Light
- Clean, bright interface for maximum readability.
- Perfect for dashboards, productivity tools, and applications used in well-lit environments.
- Uses Fluent-inspired colors with balanced contrast for text and icons.
FluentUI Dark
- Elegant and immersive dark mode for reduced eye strain.
- Ideal for developers and users who prefer a low-light aesthetic, or for apps used after hours.
- Accent colors pop against deep backgrounds, creating a strong visual hierarchy.
Both themes share the following benefits:
- Full compatibility with Wisej.NET’s built-in theming engine.
- Designed to maintain legibility, accessibility, and a consistent look across browsers and devices.
- Made to feel like a natural extension of the Fluent Design family — meaning your users should feel right at home.
Built for Flexibility
One of the hallmarks of Wisej.NET is its powerful theming system. Here’s how FluentUI Light/Dark fit into it:
- Both themes are packaged as standard Wisej.NET theme files, so you can add them just like any other theme.
- At runtime you can switch between Light and Dark modes, giving your app full support for user preference or system-wide dark mode settings.
- You can extend or customise the themes (e.g., adjust accent colors, fonts or component appearances) using the Wisej Theme Builder or JSON mixins.
The FluentUI theme files will be made available together with the release of Wisej.NET 4.1.
