Introduction

Wisej.NET is the most advanced, enterprise-scale, ASP.NET and ASP.NET Core development system in .NET. It covers just about the entire spectrum of features that business developers need to build and manage complex web applications.

It also supports rapid web development through its pixel-perfect WYSIWYG designer, integrated into Visual Studio, and its familiar component object model.

Developers can achieve in a few days what would take months, if at all possible, with any other web framework. The power and versatility of Wisej.NET also mean that it's a large and sophisticated system, with hundreds of features and several ways to accomplish most tasks.

Documentation

The documentation is a set of cross-linked books. The tabs at the top of the page open the core books, and every page links into the others wherever a topic continues there. The search box and the MCP endpoint cover all of them at once.

Book	What it covers	Read it when
User Guide (this book)	Getting started, the concepts behind a Wisej.NET application (startup, sessions, theming, JavaScript integration, security and more) and a guide to every control and component.	You're learning Wisej.NET, or you want to know how a feature works and how to use it.
Developer API	The full class reference of the Wisej.Framework assembly: every namespace, type, property, method and event. The reference for the previous release, 3.5, is kept alongside.	You know what you need and want the exact signature, the default value or the list of members.
Deployment	Publishing a Wisej.NET application to IIS, Apache, nginx, Linux and macOS, Azure and AWS, or as a self-hosted or standalone application, plus Visual Studio publishing, load balancing and server debugging.	You're taking an application from Visual Studio to a server.
License	The license model and agreement, the Technology Partner program and a licensing FAQ, with a calculator that prices a configuration.	You're choosing, activating or renewing a license.
Examples	Runnable Visual Studio solutions, one per module of the LearnWisej courses, with the source on GitHub.	You learn best from working code.

Start from one of the books below. Extensions, Hybrid, System.Drawing.Managed and Theme Builder cover products and tools that extend Wisej.NET, and they have tabs of their own, which replace the ones above once you're inside the book.

Extensions

Ready-made controls and components on NuGet: charts, editors, maps, calendars, ribbons, device APIs, icon packs, and the premium DevExtreme, Syncfusion, Kendo UI, Ignite UI and Webix integrations.

Examples

More than a hundred complete sample applications from the LearnWisej courses, each documented with what it builds, what to click and which file does what.

Deployment

Taking an application from Visual Studio to production: IIS, Apache, nginx, Linux and macOS, Azure and AWS, self-hosted and standalone, with load balancing and server debugging.

Wisej.NET Hybrid

Native iOS, Android, macOS and Windows apps built with .NET MAUI that run Wisej.NET user interfaces, locally or from a server, with access to the device.

System.Drawing.Managed

A fully managed, cross-platform implementation of System.Drawing, so drawing code runs on Linux and macOS without GDI+.

Theme Builder

The visual editor for Wisej.NET themes and theme mixins: colors, fonts, images and the appearance of every control.

Idea Lab

Curious where Wisej.NET is heading? The Idea Lab shows the product concepts the team is exploring — a new generation of native controls, the designer in VS Code, JetBrains Rider and Kiro, AI-assisted theming and component creation, a server and session console, stateless scale-out hosting — and asks which of them would make your applications better.

The Idea Lab is where the Wisej.NET team shows the product concepts on its mind: illustrative previews you can look at, kick the tires on, and react to. An exploration, not a roadmap — your feedback goes privately to the team and helps shape what ships.

• A new generation of native controls
• Design and compare themes online with AI
• The designer in VS Code, Rider and Kiro
• AI-powered component creation
• Server, session and analytics console
• Stateless, scale-out hosting

MCP Endpoint

The documentation is also available through an MCP (Model Context Protocol) endpoint, enabling AI tools and agents to access it directly as a structured, queryable source. Instead of relying on static content or embeddings, MCP allows real-time discovery, search, and retrieval of authoritative information. Use the following endpoint to connect your AI client and interact with the documentation programmatically: /mcp.
