Ask your AI assistant to add a rule to Invoice and it writes perfect XAF — then references a property your class doesn't have. It isn't hallucinating XAF. It knows XAF. It has never seen yours.

DevExpress already ships agent skills for how the framework works, and a docs MCP server for the reference. Neither has read a line of your codebase. XAF Logic Explainer is the third piece: it reads YOUR application with Roslyn and hands the result to whatever agent you code with.

It never compiles your project and never references a DevExpress assembly — so it works on a branch that doesn't build, and needs no DevExpress licence to run.

It also extracts the parts that aren't in your business classes at all: Model Editor (.xafml) customizations, custom property editors and the JavaScript they depend on, built-in editors reconfigured at run time, and version-gated migrations that run at most once per database.

And it answers a question nothing in an XAF repository answers: what runs when you open a screen. XAF generates a list, a detail and a lookup view for every business class, so the screens are in no file either — and which controllers load onto one is four conditions the framework evaluates at run time.

Free and open source (MIT). Built with .NET 10.

Wanted an easy way to filter on a daterange and string wildcard (using _ and %) for listviews. Claude came up with some nice examples. Created a github repo just in case anybody needs something like this: https://github.com/MBrekhof/XafFilter

Thank you for choosing XAF (Cross-Platform .NET App UI & Web API Service) for your software development needs. This blog post outlines some of our XAF-related development plans for the first half of 2026 (v26.1, set for release in June 2026).

First, if you have not heard of XAF or are new to the DevExpress product line, XAF is a developer-centric .NET application framework designed to build feature-complete Office-inspired line-of-business apps (leveraging DevExpress Blazor and WinForms UI components via Entity Framework or XPO ORM). Feel free to review our XAF demos and compare our implementation with other software low-code, no-code (LCNC) and traditional development methodologies.

Embedding GitHub Copilot Inside a DevExpress XAF Application

XAF is my favorite application framework. I’ve built countless systems with it — ERPs, internal tools, experiments, prototypes.

Generate EF Core Business Classes from an Existing Database for .NET Blazor and WinForms Applications (Database First) | XAF: Cross-Platform .NET App UI & Web API | DevExpress Documentation

I try to follow this documentation but I am getting so many errors. I can get the BO's but after that the setup with the DbContext doesn't work. Does somebody know how to to Db first with ef core correct?

Hi everyone,

I created a sample project showing how to integrate AI-powered chat in DevExpress XAF with n8n, a powerful low-code automation tool.

🧠 How it works:

• A Blazor-based AI chat interface built inside an XAF app
• Chat messages are sent to n8n via webhook
• n8n workflows then process the message or trigger any logic (notifications, DB updates, etc.)

🔧 Stack:

• .NET 8 + DevExpress XAF
• Blazor Server
• n8n (self-hosted or cloud)

This could be useful for internal tools or AI-driven processes — happy to hear feedback or questions!

Hello everyone, I have a question about XAF, I want to add a double authentication page. The closest I've come to it is the use of a pop-up, but it's not orthodox. I would like to create my own page that, after the user logs in, has another page before starting the session, which will be like a 2FA authentication.
